Find a leak
New to the forum . I have 2007 Jayco Greyhawk 31 ss i have leak in both corners of the bunk over the cab. I put a tarp over the seam area even though the sealant looks ok. Today I went to look at it and still have leak. There is no sign of it in overhead ceiling. Anybody have a similar issue ,know of a fix.
Thanks so much..

Could be the clearance lights. If you have a dealer close by have them do a "SEAL-TECH" test.

X2 on the exterior lights. Basically a hole drilled into your shell with a wire or two coming out. If the base is not caulked properly or the snap on cover is not tight then they will leak (not might, will).
Run a bead of dicor or equivalent but never! Silicone! all the way around it and if you have a non-led fixture see if the cover is tight. If you caulk down the cover apply sparingly so you take it off to replace the bulbs.
Wind at 65 mph can drive rain up under things so all 4 sides need to be sealed.

Put together your our leak detector. I did with an 27' Award tt I couldn't locate a leak.
All it takes is to positive pressurize your tt, soapy solution and spray bottle. It will not hurt anything and you will find the leaks.
I happened to have basically a dust collector that I rigged the exhaust hose to my tt, turned it on, waited a bit and began to squirt soapy solution in areas I thought might be leaking. Found them and fixed.
Got the idea from a reverse of a test local electrical company offered on our house, they used negative pressure and used smoke to find drafts. Remembering this I thought why wouldn't it work in reverse?
Well it does, try it.

PaulB12, I like that idea!
Clearance lights are a common issue. If you removed the lens cover, and then remove the mounting screws. If they are steel screws (usually are). If they show signs of rust, you got a leaky light fixture.
You do not mention if the signs of water is up high along the main ceiling or down low along the bunk mattress area (cab roof joint). Over the years number of people have posted issues between the joint between the chassis Cab and the fiberglass MH shell. Well worth taking some time to inspect.
Sure you already have, but check the gutters, corner joints, etc.
Remember water flows down hill, and will take the route of least resistance. Parents had a TT, that had a water leak in the ceiling. They looked for it for years and could not find the source. It did not leak with every rain storm. Final found it while doing some remodeling work. It was the TV antenna. Water leaked in through the antenna mounting frame, followed the cable until it touched another wire in the ceiling, then followed that wire until it touched a truss frame, which then allowed the water to touch the ceiling board. If I recall it was about 8 feet from the antenna where the water signs of water was at.

Looking at the site given a few posts back is what they do. But for $5,000.00 only a dealer could afford, then what do they charge$$$$.
A squirrel cage type fan would work. Be patient....the bubbles will appear!

I just posted their site to show you what i was talking about. Some people say "HUH" when you mention Seal-Tech since there are several companies with the same name.

No problem, I was pointing out it is a DIY job. Hardest part is hooking it up.

If you have exhaust fans that can also reverse the air flow (intakes air vs exhausts air), it is an easy way to pressurize your rig to find leaks with soapy water.
