Looking for info on who made it ? cant find it on the internet

Manufactured by now defunct Coachmen Industries.

Make a note that the original engine is a leaded fuel engine.

Thank you ! That is what I suspected due to the stagecoach emblem with Concord superimposed on top of it but wasnt sure ! I also need to find out if it has the 413 in it as opposed to the 440 I have been told is in it ? I know there is a cutoff year of either 72 or 73 for the 413 ! I am trying to find what Master Cylinder is in it  ? I drove it home 150 miles with only front brakes and they went out half way home lol ! I had my roommates stay in front of me in my car  and another one behind me  so If I hit anything I would be alright lol ! Got home safely and the next day I went to move it and wrecked it by sideswiping my cousins freshly restored and painted pickup ! The paint wasnt even dry on it yet lol

I am seeing references on some of the "vintage sites that are stating that some of these have 2 Master Cylinders ? I am disabled so I have to wait and find someone to help me fix the brakes  !  getting down on the ground is not the problem for me , Its the getting back up that sucks lol

The engine sounds fine but wont idle , The guy I bought it off of said he had just rebuilt the Holley 4bbl on it ! I am planning on all new plugs and wires and such !

Once I get the brakes and tuneup done I am going to need to suss out the Onan Genny which he said needs a rebuild carb also ! then once thats all up and running I need to check out all the electrical BS ! Supposedly everything else works but I have yet to see it working with my own eyes  ! He wanted $700.00 I gave him $500.00 and turned his headache into mine lol !

Thanks for the prompt reply

P.S. , Leaded fuel engine ?? Does that mean I cant use unleaded or do I just have to use the higher octane fuels ??

1973 was a transition year for MoPar, suposedly used hardened valve seats starting in 1973. That means one can use unleaded fuel. Compression ratio was usually low in the RV's so regular unleaded has worked for me with a 360. Another question would be, is that the original engine, or one from a car? The RV blocks were a heavy duty version, and are identifiable by casting numbers.

Of you want to research this, go to www.allpar.com.

Seems I may have been wrong on the fuel. I was under the impression that hardened seat in 440 was retooled at the engine plant in late 76. The 413 was nicknamed a "wedge".  As far as the original equipment. theres a chassis VIN stamped in the frame passenger side front suspension. You might get lucky and still have the fargo tag mounted inside driver side engine cabin.
