Well. as we all know,, way to well, It has been a realy wet rainy winter here in the south, At one time thought about building an Ark. On one occasion, we had high winds, and buckets of rain hit, and of course, 2 elusive leaks,, one in the bathroom vent and the bedroom vent. Well, it seemed like the rain had found a way into the trailer around the seal or the cover itself, One would think, That was not the case after taking the vents completley out and inspecting .From the ceiling up it was dry,, but the ceiling board was damp/wet. Which mean, it was a traveling leak, Picture a leak at the front of the trailer dripping down and after tracking it,, its coming from the very back corner,, Leaks are great migraters,, they can travel very long distances,,, they are smart that way,

Well, up on the roof Im looking at everything possible as to where this elusive leak ,which I properly named PITA... Now PITA is like a cockroach,, very clever and elusive. I found PITA hiding in the toilet vent pipe, under the rain/debri guard..I removed the debri guard and look down and by golly jeepers,, that lil rubber seal donut ring was dry rotted and crumbled. Its a big taper ring that goes around the black vent pipe and seals onto the roof, With it being damaged, it was allowing water to go between the vent pipe and roof and inside along the ceiling to designated vents. So before the next round of rain hits, I get out the ole sealer and snot it in there real good,, then added some more for good measure,, and just a teensy bit more, jus cuz, Then put the debri cover back on and sinse I was outta snot sealer, I had to rely on Silly cone, (OMG, not silly cone).. Yes Silly cone,, But it was only goobered on the sealer tape that was wrapped around the debri cover, so no issues with getting that stuff off later when I order a new debri cover, (I think-did gooders) So this is just a heads up if any of you get an elusive leak, Like my PITA,, check your toilet and sink vent tubes.and makes sure you have a good seal where it protrudes up thru the roof.   Happy trails,,,

Just used Sikaflex 116 ro reseal my vents, only used enough to get a good seal. Too much just collects water where it can't be seen!

These types of leaks are really elusive!

You should look back on Russ Johnson's post with his former MMP. That would be the definition of silicone overload and how not to seal an RV.. He found it everywhere when he was trying to rehab his class A. It had to be that way from the factory.

Hey Lakota, Got one final one lurking up front but betting it's the main body joint that is where the fiberglass front joins the aluminum frame. It's one joint going all across the front cab on the roof and down the sides and it's SLATHERED in sillycone. Can you imagine that??
