Sidewall Delamination - Could a minor fender-bender cause it?

So, about three weeks ago someone was backing their car out of a parking space and ran into the side of our RV. The impact was mostly on the rear passenger side bumper. Several days later (one week) we noticed for the first time, sidewall delamination in the general area near where the impact occurred... Could this accident have caused the sidewall delamination or do we have a water leak or manufacturing issue, etc.? Thoughts? Thanks.

I'd think the delamination might have been in progress and the stress of the accident made it more noticeable as you paid more attention to the area damaged. You could try making a claim under insurance, but I don't think I'd hold my breath.

According to your public profile, it's a 2006 RV. You might have had a case that it was a manufacturing defect, but only until 2007. Inspect around windows and other items that penetrate the sidewall in the delamination area, also the seam between the roof and the sidewall. There are many places water can enter if you don't keep up with caulking.

If they only hit the bumper, I wouldn't think so. Otherwise any possibility that it may be related would be dependent on how close the impact was to the delamination and unless the point of impact and delamination are the same, ain't no way insurance will even consider it.

I can see how it would cause that, lamination is not the strongest thing out there.

Different RV's use slightly different construction however most of them use Styrofoam or Polyurethane, neither of which have any shear strength to speak of. Impact could easily cause it to separate and so could water damage. You could also have a void between the outer skin and the core to begin with. Sunlight heats up the air in the void and causes it to expand. That causes the void to grow larger over time.

Can you post a picture of the bumper impact and the sidewall delam? This would help if you want good opinions.
