Bubbled Fiberglas

Where is it exactly - front, back, side?

Driver side, about a foot from a window, at about 4 o’clock...

Sorry but you just lost thousands in resale value!
Delamin8is most of caused by moisture in the Luan behind the fiberglas! Maybe a minor leak around the window.

I will not buy an RV with WOOD backed fiberglas!

Kind of severely limits your choices then, in as much as 90% of them today are vacuum bonded fiberglass (Filon) over wood substrate.

I'ts delamination for sure probably cause by water intrusion from a leaking window seal. Seals and caulk need to be checked and maintained a couple times a year, something very few owners do until bad things start happening. The they 'reactive' instead of being pro active.

The thing to do as soon as possible is to find out why to prevent further damage. More than likely there is a leak somewhere. If so, it will get worse.
If it is as HuntingDog said, it may or may not get worse.
A pressure test will show you if there are any leaks.
Good luck.

Exactly.....wood backed fiberglass as opposed to what? Azdel backed fiberglass ( which still can delaminate and is a lot of marketing rigamarole) or stick and tin ( which the siding can have water blow through the s lock seams if it does not blow off completely from the factory idiots blowing staples clear through the nail flanges, not to mention caulk joints that have to be thicker and backed up with succesive layers of butyl tape to account for the highs and lows in panels)?

Looks like Bob wont be buying any RVs. They're all junk when you get right down to it lol.

It's interesting Ralph, that the level of 'junk' isn't commensurate with the price either. You can buy an entry level RV and it's good to go or you can buy a high end one that leaks like a sieve and is falling apart inside. No rhyme nor reason other than shoddy workmanship and lax maintenance on the owners part.

I've seen countless RV's parked outside uncovered in the winter around here, loaded with snow and seen them in the same spot in the summer, untouched and I know they are deteriorating.

Mine stays inside under roof when I'm not using it and I check all the seals and caulk couple times a year. I expect mine to last at least 10 years, my previous one was 15 years old when I sold it and I got top buck because it was tight, dry and everything worked but it had to be maintained. You maintain your house...You maintain your vehicle, you maintain your RV... all the same deal.

Around that time there were a lot of RV's having problems with the adhesive bonding the wall. So it may not be a water intrusion problem at all.

May or may not be but I'll put my bet on water intrusion. It has some age and probably little pro-active care.

I've looked at many older units and they all have one thing in common. Water issues number one, oxidation of seals number 2 and rotting sub floors number 3.

Before I bought my new one, I was a Craigs List junkie but I took along my IR camera and thermometer. Was amazing what I found under the 'covers'.

Even new units are suspect today. After all, they sit outside from the time they are built to the time they sell at a dealer, exposed to the elements.
