Fixing camper water damage?

Anyone have opinions on buying water damaged trailers?

I found a triple axle toy hauler for pretty darn cheap, but it has a LOT of water damage in the nose portion. Its a bumper pull WW toy hauler and it looks like the siding has opened up on both sides of the front of the trailer. The owner says the front bedroom probably needs to be completely pulled out for inspection. Sounds like quite a bit of woodwork.

Its a fiberglass shell and probably has stick framing and plywood. I would probably need to pull all the wood out and start fresh – studs and OBS. The fiberglass shell looks good but i would need to pull it back in and reseal it.

Any opinions would be appreciated. This might be a good opportunity to go from camping in my car hauler.
