So if one wanted to rehab a Class A M.H. that has much delamination and a roof that leaks, how can you replace all that material and stop it from happening again down the road. I say this because the original manufacturer wasn't able to build these Class A's in the 90's from keeping this from happening. I can buy a 92 Corbra Monterey for $1,200.00 and I have a friend who is very gifted repairing anything and he already has the roofing material, but how can you stop water from finding its way through the outer shell and causing all kinds of damage? Any advise will be greatly appreciated. The Monterey is on a Chevy P-30 Chassis W/454 V-8 & TH400 3 speed tranny! Bagman.

In my opinion, you can spend a lot of time, and money, and even after it is repaired, the 1992 Monterey may still be only worth $1200. I believe the only way that you can properly repair delamination is to completely remove the side wall, take it apart, replace all damaged wood and insulation foam, apply a better adhesive, and then put it all back together again using compression to hold the sidewall flat while the adhesive sets up. To me this is not s DIY project and should only be attempted in a factory type environment. Even then, the time and materials involved would NOT increase the value of the coach being repaired. Of course, there is probably interior ceiling panels that also have to be dealt with as well as rotted floors from the leaks. Stopping a roof leak is pretty simple basic repair work. Dealing with the delamination and other damage that has already taken place is the huge problem.I would find another project Class A without delamination issues.

If the roof is replaced and properly sealed/maintained, it will eliminate the leaks and additional damage. I don't have any advice for the delam repair. I know it's a major project.

If the systems all work, and the drive line is good ...part it out on craigslist! Then look for something without leaks or delamination with the additional monies from the parting out.

This sounds like a complete money pit. Water is a killer to any structure. Even if you fixed it I would still be concerned with mold and structural damage. The amount of money you would spend would be lost because it will never be worth what you put into it. I would estimate the cost of the job (likely well over $10k) and take that money and buy something that is in decent shape with no leaks. Plenty of used Rv's out there.

I bought a 98 winne with some delam from a cracked top rear corner. Took way longer to do, way more money, and more headaches than I imagined. I never liked the looks of the repairs and ended selling for less than I wanted. It did stay dry though. Don't do it. i will never attempt again. Find something with no leaks and enjoy camping.

Yeah, I'm thinking what I would spend on repairs would make a nice down payment on a new M.H.
Good choice. Sometimes you just need to walk away and let a coach head out to the RV graveyard.

I am enjoying doing my 98 30' class a MH.My delam was extensive on pass side. I pulled the windows, dryed out the inner walls used west sys slow set epoxy poured inside the filon wall. Clamped w/1/2" panels backed by 2x2s & strapped & clamps. It set up in 24 hrs, walls are flat. Now I'm shopping for interior panels & finish. I'll prolly have 15-17G including purchase. It has 36k mi & I'll have a nice MH!

I really respect and agree with Ron's post! He's done many vehicle rehabs over the years and has lots of knowledge on issue's like these!

I did a 1988 Pace Arrow passenger side several years ago, took fiberglass and windows- door off used 1/4 inch plywood and lament glue lots of it, it likes to soak in, also used gas tank sealer on side rails, it took a lot of time but it turned out ok. It did not cost over $5-600.00 dollars at the time. I used eternal bond tape on roof.
