Seal roof leaks?

[Born2RV]

Our daughter and son-in-law purchased a 1989 Ford Econoline Crossman Class C and are nearing the end of their repairs. It had some water damage on the inside - especially up over the cab and in the back corner near the bed. My husband is just about done rebuilding and repairing the inside walls and is going to prime and paint today. Looks GREAT!

Before they actually take it out of our barn and on the road (it was stored outside for years by the prior owner - therefore the damage), what is the best way to seal the roof? Should they remove the old caulk and recaulk? What type should they use? What about around the windows and tailights? They plan on keeping this motorhome for about 5 or 6 years until they can afford a newer one and their children are out of daycare.

I would remove all the old caulk and do all the seams with eternabond tape. For the areas where the tape won't work use dicor.

Also pull the windows out of the wall, clean and use new butyl tape on outside flanges of windows when you re-install. Cut off excess and seal will silicone, Proflex or equivalent after butyl quits oozing out.

Have a similar problem..... over the cab on drivers side (bubble forming in ceiling) and back passenger side corner.... molding was popped off from Ice last winter while it was stored, but from looking at how rotted the wood was behind the fiberglass, I can tell it's been leaking there for a long time... The previous owner had blown the motor and left it to sit for 5 years under a tree in his back yard before moving it (not sure how he moved it) to the front yard, and put the for sale sign on it.... he also scavenged (pirated/pilfered) the generator as well.

As well as over the side door the wood is rotted and decentigrated. I'll be digging the rotted wood out and slipping some one by material and glueing them together at the seems, then replacing the molding over it. and replacing all the silicon around the windows and seems. I wasn't planning on pulling the windows out, but.... might be worth doing it right, instead of just trying to be done...

I picked up a generator to replace the missing one, but I think it's a little bigger than the opening, and has to be wired by someone who knows what to do with it... I'ld hate to put it in and either not have it working right, or worse, burn my rv up... I ordered new deep cycle batteries for the 12 volt system (buddy knows someone who can get them at a discount if I don't might them with a blimish or what have you (scratch and dent specials I guess...)
