Back in November after much searching for an older Class A to restore, I ended up getting a '92 Winnebago Chieftain in great condition for its age. Everything works, it runs and drives good, and was obviously well taken care of by the two previous owners.

Best of all, it has no leaks, and no sign of ever having any from what I can tell so far.

What is the best way to keep it that way? I have done some searching, and it seems like there are several options. Would love to hear your thoughts on different products/processes. I will be doing all of my own work, and have the tools and shop space.

Thanks in advance!

I used Eternabond tape on every seam and opening I could get to. Mine wasn't leaking either, all of the 'caulking' was in good shape. I cleaned everything, then put 4" tape over the seams at both endcaps, around the skylight, around the fans, around the top of the ladder, probably some others that I can't think of now. Everywhere that there was caulking I covered it with Eternabond.

i I had a 1990 25ft. Classic HiLo. The walls became soft from water leaks. Here is what I learned from DH rebuilding the walls. Pull out all the windows and reseal with butyl tape and Lexel caulk on the exterior. Utube had a video on how to do this. It easily can be a DIY job. Worst part each window takes 6 to 7 hrs. to do.Currently got a 1996 HiLo. Pulled out all the windows and resealed. Discovered small area of delamination on the escape hatch window. Aplied elmers glue and clamped. One window cut out was a little big. Used a shim to fix this area. Check all exterior caulk and scrape and replace as needed.

When we purchased our new-to-us MH, one of the first things I did was apply Eternabond tape and Dicor caulk to all seams on the roof. A little water can do alot of damage.

Same as the others here...Eternabond and Dicor self-levelling sealant around the edges of the tape. No more leaks to worry about. Check it every Spring or Fall.

My first thought is to store inside if possible. The Sun is cruel to caulk, and rubber. My 95 Bounder has had leaks in past, have used Flex Tape, Flex Seal with good results. Just need to re-do spots every year or so, the Texas sun is brutal.
Wish I had a building to keep it inside.
