Allegro/P-30

A place to share information about and to get help with your Tiffin Allegro and its P-30 Chevy chassis. I'm amazed at the seemingly infinite combinations of floor plans throughout the years.

    I got a PM from Glynda on 9/18. I'd be happy to chat. I responded with my cell phone number. Let me know if you didn't get it Glynda.

    Headed to our annual trip to the Promised Land next weekend. I scooped up the Allegro from my dad's driveway today. The larger leaks that I sealed a couple of years ago have resurfaced while it sat. Very frustrating, but I know where they are. 

    I drove a few miles to the gas station with the parking brake on. Rolled up in a cloud of smoke that alarmed the pump jockey (can't pump our own gas in NJ). Had to pull off to the back of the station for a while to let it cool down and make sure it wasn't going to catch on fire.

    Other than that, the old girl seems to be ready for the next trip. Got the heat and hot water fired up tonight - seems to be in working order. 

    The generator won't stay running anymore. I need to take the carb off and clean it I think. 

  • Philip Wolsonovich

    Omg Jim you do seem to have your problem. Hope every thing else goes well. Be careful and have fun.
  • Jim Stoltz

    Thanks Philip. It's all part of the adventure. The Liquid Roof I applied seems to have shrunk a bit over the past couple of years. The roof rack on the Allegro is a classic look but puts a couple dozen holes through the roof. That's where the leaks are. I have some Dicor tape I can try. The parking brake thing was just a "duh" moment. Wondered why it was so sluggish :)

    In other news I'm getting much better at squeezing it into its spot at my "new" place. No longer a white-knuckle exercise. I know how to swing it so I can do a proper K-turn into its spot. It's still super tight, but I'm used to it now. Only hit the fence once this time!

  • Philip Wolsonovich

    I here you on the adventure part. Been trying to get my furnace to work dependablely. One actuator sticks in valve but I think I've got it. I've squeezed my baby next to the barn the biggest problem I have is the tail swing with all that over hang but getting used to it. Head down to Salt Fork state park for some Halloween camping so the furnace is pretty important.

    Gone made it back up to Cinnaminson NJ for Brad's wedding over the weekend. uneventful journey up and back thankfully.  SAIL switch in furnace still bad...  thinking I may dremel cut out a few side vent grid pieces of furnace housing so I can access the switch vs taking apart kitchen to get it out... but don't know if that will affect air flow over the dang switch.. was looking at it as I had time to Saturday morning. 

        as for roof rack and leaks.. I've been fairly religious since owning Gone about cleaning, caulking, then coating her roof with elastomerized paint every 2 years...  biggest PITA is scrubbing it and rinsing the result off the sides... before it dries.. that said I need to scrub the screw cover before this weekends fall trip.. as well as the rims..  we just plug in a ceramic heater inside until I get the furnace up and running.. may as well use the campground electricity than our propane anyway... :-)

  • Jim Stoltz

    Yes I guess it's time for more Liquid Roof. It worked great the first season. The second season I had one leak reappear. I sealed it with Dicor tape and did a bunch of other rack pedestals as well. Now I've got a few others opened back up. One of the few good things about living on a steeply sloped property is that the water runs right off the roof without fining any leaks. But it had been sitting in my dad's level driveway for the past couple of months. I have a leak by the cab that I know is the rack, but the one by the entry door baffles me. The rack is sealed with Liquid Roof and Dicor tape yet the interior light above the door is filling up with water. I thought it might be the fridge vent but it's sealed up pretty well too.
  • Cristina Gouin

    I had the roof rack leak from where the joints were in the top of hte rack.. not the pedestals...   The only worry about sitting not level is that the fridge if RV type needs to be parked level or nearly level.   my drivers side window up by dash has a leak the sill is always full of water and the paneling around rotted but know that is a can of worms... so reseal around it with silicone after cleaning it next dry time agian... always something. 

  • Jim Stoltz

    So the water comes in that joint and then down in through the pedestals? I hadn't thought of that.

  • Jim Stoltz

    Oh and the fridge - I know. When I turn on the fridge I pull it onto the driveway and level it. When it's not in use it's parked in a dirt/gravel spot where it's impossible to get it level. The water runs off the left, rear corner which coincidentally keeps the water away from all the trouble spots.

  • Cristina Gouin

    yup had a leak over breaker panel in bedroom... was from the rail joint... after inspecting painting sealing every thing possible on the top of the roof... finally saw that... sealed that.. no more leak.  I'm usually up on roof yearly wiht a tube of white exterior caulk and a clear tube too. LOL...

  • Daniel Long

    Has anyone had luck using the Rustoleum version of that Leak Sealer spray? I used it a lot on the Tioga and that product actually had a true white instead of a almond white. The spray seemed to do the job really well as long as you didn't overdo it.

  • Daniel Long

    Okay, getting all systems up and running and I cannot find the actual fuel capacity for my Allegro's fuel tank! She's a P30 chassis, 1987 with a 454 Chevy. I measured the tank on the driver side and get approximately 15" high x 28" wide x 67" long!! Wow! That's about 28,000 cubic inches taking into consideration considerable tank wall thinkness. At 231 cu. in/ gallon you get about 121 gallons! Is this right? I've heard everything from 75 to 110 gallons for this model. Anyone know?

  • Jim Stoltz

    Mine's 85 gallons, but I don't know the dimensions. I don't see anywhere in the manual where it says that, but the guy that sold it to me knew somehow. It seems about right based on fillups and usage (my fuel level gauge doesn't work).

  • Jim Stoltz

    Mine seems to be holding up okay. One of the straps is pretty well rusted. I think my generator standpipe has holes in it too. I have to have over 1/2 a tank of gas in order for it to run. How did you get the tank out? I pulled the straps off and the thing wouldn't budge. I also don't see how it would drop out with the filler neck on it, and I don't see how you could remove it.

  • Jim Stoltz

    Firmed up my NASCAR plans. I'm thinking the early-June race will be the first time out for the season with the old Allegro. I fired it up today and made a list of things to do between now and then. De-winterize, sanitize, change all the fluids, get more propane, etc. and so on. 

  • WILLARD STOTLER

    putting new air bags & shocks on our beast not my favorite thing 

  • Daniel Long

    Just ordered KYB shocks and tested my front air bags and they both leak like sieves. Time to get new ones! Glad I've seen the install done before.

  • Jim Stoltz

    Ugh. I do need air bags. It's the one thing I've been avoiding since I got it. I have a pair - new in the box. Maybe this will be the year I actually do it. Maybe even before the Pocono race!

    A bit higher on the priority list is one of the rear bags has a pretty good leak. The rear bags ARE the suspension in the back (no springs) so I need to fix that. As long as it's running it's fine - the compressor keeps it topped off. But if it sits for more than a day it drops right to the ground. I had just pumped it up in that pic I posted.

  • Daniel Long

    Luckily mine just has the leaf springs in back.No compressor.  Low tech but I don't have to worry about 2 sets of bags! The guy on YouTube has some really good videos of his coach (P30 chassis) to look at and get a feel for the repairs. His handle is "Class A Living".

  • Philip Wolsonovich

    Trust me make sure they are the correct airbags. The first set I got were in the correct box but someone packaged them wrong. Use plenty of soap and patience. You hands will be sore after but the ride is worth it. Oh and it's not as easy as in the video. Good luck.
  • Daniel Long

    I hear you Phil! Every time I order a chassis part like shocks and such I always have to double-check that it is indeed for my motorhome. Even the shocks I ordered said, "not for mono-beam suspension motorhomes" but mine has independent front suspension. Bet they just meant, "forget it, this ain't for any motorhome". Same size, capacity, etc. but something will be wrong with it! Argh!

  • Daniel Long

    When working on my Allegro. I follow some simple rules for repair and fixes. 1) Research as much as you can and know that you will run into something not covered in the manual; 2) the repair job will NEVER be as quick and simple as everyone tells you it will be; 3) assume you will break something that will require additional purchases or fabrication work; 4) accept that many times the application of the wrong tool will not be as good as just getting the right tool for the job; 5) you will get dirty.

  • Jim Stoltz

    Thanks Daniel. I found his video here: https://www.youtube.com/watch?v=vE20DUy5njk

    He has some cool videos. I wonder what the springs are attached to his lower control arm? I don't have that. Some sort of stabilizer?

    I got "Air Ride" bags - supposedly the correct ones.

    My rear bags are part of a Jet Ride system installed by the original owner. Back in the day, it was an obscenely expensive air-ride system that for some reason he thought was necessary. When it works it's great. But it's far from maintenance free. There are leaks all over the place, but none are so big that the compressor can't compensate. The good part is that I have a wide range of up/down and side-to-side adjustment in the rear. It keeps me from scraping (much) on the steep approach to my driveway.

  • Philip Wolsonovich

    Be sure to inflate slowly and re-ajust as necessary. It's a bit tricky but they do seat nicely in coil spring. Be sure the valve stem is as straight as possible before final inflate. My air bags hole air for about four months before needing a few pounds.
  • Philip Wolsonovich

    A sawzal works great for getting old bags out. The instructions show pulling the intact air bag out bottom hole. Trust me the old bags are so stiff that won't happen. And put the top plastic piece in before the air bag gets to car in or it's a real bugger.
  • Philip Wolsonovich

    I'd love to get those rear air bags come day Him. Would save storage space from all the blocks and be a whole lot easier to level.
  • Jim Stoltz

    Phil - yes it is pretty easy to level. I carry ramps anyway. I try to spitball it with the ramps first, then finish up with the air bags. Combined with the ramps, the bags give me a pretty big range. The rig is almost level in that pic and it's basically hanging off a cliff.  

    I do plan to hack the old bags out with a sawzall. There's not much left of them. I really would like to get this done before the next trip to see how much of a difference it makes.

    I also got a flow-through TPMS system that monitors air and temperature. I'm super paranoid about a blow out so I figured it was a worthwhile investment. I need to get that installed too.

    My gut tells me to check the rear brakes too. I haven't looked at them since I bought it. They work okay but it can't hurt to take a look back there. Thankfully it has discs in the back so it's easy to work on.

  • Philip Wolsonovich

    Oh man I wish mine had disc in the back. Mine are drums and you have to remove the axles to take off the drum.
  • Jim Stoltz

    I guess I dodged a bullet on that one. I was kind of surprised to see discs back there. I had no idea you had to remove the axles to remove the drums. A buddy of mine has an '87 28 footer with drums. I never thought to ask him about it.

  • Jim Stoltz

    Daniel - I was watching that Class A Living guy's vids and he spotted this in one of his boondocking vids. How cool is that (I grabbed a still frame from the vid)?

  • Daniel Long

    LOL! I saw that Allegro with window awnings and commented on that to him! Guess we Allegro owners all have that knee-jerk reaction to seeing them in other people's videos.

    :-)

  • Jim Stoltz

    Yeah those window awnings are a lot of work - someone spared no expense on that one! I'm always excited when I see another vintage Allegro. People seem to like to see them out and about too - they're antiques now (just like me I guess)

  • Jim Stoltz

    Also what's interesting about that pic is that he has the power cord out. Is he grabbing power from somewhere? Or maybe hooked up to a generator off-camera. Either way, that parking lot is pretty liberal with their camping rules. Need to be a lot more discreet here in NJ.

  • Daniel Long

    Just like Forrest Gump, " I got me new shoes!" for the RV of course!

    Glad to have new tires vs. the original (yes, never changed in 30 years) ones.

  • Jim Stoltz

    Wow! Mine were visibly dry rotted when I got my Allegro and they weren't originals as far as I could tell. Do you have 17s or 19.5s?

  • Daniel Long

    Mine are 215/85 R16. Big bubble tires but they help the ride quite a bit. The tires I replaced had the old 7.5 x 16 designation on them from the 80's. Glad to have them off the rig. Just waiting for my spare to show up then I'm done with the tire stuff. The old ones were  "D" load rated, 8 ply. These are "E" rated 10 ply.

  • Jim Stoltz

    Pulled the Allegro out of its hibernation spot today. It was starting to sink. Right rear tires spun a bit but nothing dramatic. I got it out onto the pavement, repositioned the 2x12 planks and put it back. I crawled under it to put a jackstand into place and saw that the left rear shock had broken loose from its mount on the frame. Not sure when it happened but based on the hammer marks on the underside I'd say a while ago. Need to add it to the to-do list.

  • Jim Stoltz

    My stepson and his friends use it to crash in on the weekends. I don't think they realize it actually moves.

  • Philip Wolsonovich

    If anyone is interested I have two captains seats and two seat that go in the back that aren't mounted. They would need cleaned up or recovered but are in decent shape. $50 for all four. Let me know if interested or would like photos.
  • Martha Toler

    Ok, all you RV guys and gals , hope your summer is great and your Allegro's are running smoothly and giving you great pleasure. My family and I have used ours several times checking out camp grounds around North Carolina and enjoying the heck out of it. We are still doing a few tweaks and minor stuff to it, and want to continue doing more until it's almost back to where it was 30 years ago. When we bought it back the first of 2016, we were more worried about getting it road worthy, and that we have accomplished , but would like to have the Allegro trademark on it, as currently there is not Allegro anywhere on the outside. I have a friend that has a vinyl business and and all I need is the dimensions on the lettering and I know you guys have it on yours. Would love the height( overall and width of lettering! Any help you can give me would be so much appreciated!!

  • Daniel Long

    Martha. I've got two original side plots from Tiffin from that era. The paper backing is solo old I'm afraid it won't stick so I just saved them. I could color scan them at full size and send that to you for the vinyl shop to make one.
    Daniel.
  • Martha Toler

    Thank you Daniel, that would be great!! Would you be able send it via file on here or do you need my private email? I thank you so much and if you need any compensation, please let me know. Laine1032@ yahoo.com.

  • Jim Stoltz

    If it helps reduce the costs, I'd go in on a decal for mine. I only have one - it's on the front, on the driver's side. Is that the one you're having made up? I'd like to paint my nose but don't want to ruin that decal unless I have a replacement.
  • Daniel Long

    I can bring it in tomorrow am and then send it out to you. Ill try both jpg and off versions.
  • Daniel Long

    Autospell stinks... I meant PDF.
  • Martha Toler

    Awww, thank you so much Daniel!! Not sure where my son wants to put it, I', thinking across the nose/front end, if it will fit, but not sure. If I can get several made up at a reasonable price Jim, I will let you know and contact you! Thanks again for all your help. On a different subject, one of the airbags on front is bad and my son has the replacement already, but might need tips on the installation, any good ideas? Thanks

  • Philip Wolsonovich

    I would also be interested in those decals if you let me know how much. Also the front air bags need liquid soap and strong hands. You put the soap on the air bags and twist them like a cork screw then screw them up through the bottom A arm. After than inflait them slowly and position them with the valve stem in the center of the A arm hole. Patients is a extremely important here. I found a sawzal was best for removing old bag. I just did mine last year ounce they're done you'll love it.
  • Daniel Long

    Hey Martha,

    Logo files are on the way to you in PDF. I can get them to you in other formats now that I drew it in CAD.

  • Daniel Long

    On those logos.... in order to avoid some sort of copyright I'd either change the size slightly, color or change the text below to do something fun and unique. Also wouldn't be selling them, just charge cost for the restoration printing.
