Because I was ignorant when it came to what to look for when buying a used RV we purchased a Arctic Fox fifth wheel that had the floor plan we wanted. What we were not aware of at the time was how poorly maintained the unit was and the dealer, of course, said nothing.
The result was there had been roof leaks causing some portions of the siding to start separating from the plywood, not too bad but obvious when one knows where to look. I have since had the roof reconditioned and thoroughly caulked and sealed.
Then I noticed a crack of about 6 inches on the sidewall at a corner of a slide. That too had pulled away from the underlying plywood. This one will be difficult to fix and may be impossible.
Bottom line is we are not sure we can even get rid of the unit or will just have to write it off. One more example of buyer beware. One really must do their homework or they will be at the mercy of the dealer.
Here is an article on the subject:
RV Delamination And Cracks: Both Are Serious Issues
My first reaction was to never buy any fiberglass sided RV but have since reconsidered. At this point I believe it was the extremely poor maintenance and hard usage that was the source of the problem and not the manufacturer's.
My search for a replacement will give points to a metal sided unit but will need to do more research to see if any brand may be more prone to fiberglass sidewall problems than another.
To say this is annoying is a masterpiece of understatement.
Sure glad I found irv2.com
