1998 Bigfoot 2500 series

Hello, 

i just recently got a bigfoot and noticed there is some delamination bulging on both sides 1 is very slight and the other is quite noticable on the right side right above the fridge access so top right, ive seen people say it could be due to sitting on jacks for a long time witch would make sense but there seems to be water intrusion on the windows, i was told it was bought from an estate sale so who knows how long its been sitting on jacks but the roof and mainly the sides seem pretty good.

I know im going to pull the sides and fix it some time soon but concerned taking it on a trip if the wooden brace is compromised, really wanna get a couple trips it before i do so to feel it out and swap or install things when i do so

    what do you mean by delamanation?  bigfoots won't get the traditional delamanation like other trailers as that is the thin fiberglass board delamanating from the foam and frame and it looks like a giant air bubble.  it is pretty much a rare thing now but still happens.

    with a big foot or NL or any other pure fiberglass clam shell design you will get actualy fiberglass failure, and the proper way to fix it is to grind it out then re-filberglass to build it up again.  you could just inject resin into the part that is seperated but thats just a bandaid and no guarentee that it won't keep going.  with your kind of rv it is more constructed like a boat.  for repairs on the shell reading up repairs on fiberglass boat hulls would be the best advice I could give you.

      Gotcha, just to get and understanding, what contributes to this ? I see the right front leg is kinda kicked forward. Not sure if that has anything to do it. Just wanting to get a understanding to make sure it doesn't happen again
