delamination of the back wall

Hi Chuck I have a passport 195. They are made with the floating rear wall. Mine is anchored with a rear window and the water heater. You have nothing to worry about unless the wall sags and then you will see a bulge along the bottom in line with the bumper. No bulge, no worries.

Had the same issues with our Heartland TT. Only the sides are vacuum bonded or pinch rolled. The front and rear are sandwiched with the trim, window/vents, etc. The front was rolled over the radius framing and held by trim and lights. The front puckered in a few places. Also had the same puckers in the rear.

If the whole wall is floaty, then no big deal. If you have bubbles then you have delam.

Many of the Keystone products have a "floating" rear fiberglass panel. That is the way they are designed. The panel is fastened around the perimeter and around any penetrations on a conventional stud wall with fiberglass insulation.

As a few others have posted - in several trailers the back wall fiberglass is not mounted to the back inner wall material. As such, you can "jiggle" the fiberglass.

I would call the manufacturer and take it to a neutral 3rd party dealer for an inspection.

Vacuum bonding uses glue/resin between the layers and then applies a vacuum and heat to make the "sandwich" cure. It is very solid but as mentioned leaves no room for wiring after the fact. If that method is used wiring is done ahead of bonding.

You can push on it and the skin will move in and out slightly. It may also have a somewhat pillowy or puffy look to it. It wont be as solid to the touch as the sides are.

I suspect it is as Joe indicated above.
The back wall is not vacuum bonded so it's easier to run wires for the tail lights, running lights, etc.
Many brands are built like this. I don't think you have a problem.

Some brands of trailers do not use a bonded back wall. Why I don't know. Go and look at some new ones,you will see what I mean. Unless you have water damage I don't think you have anything to worry about.

You might try to resolve this issue with the seller. If he is a dealer he just might work something out with you and do the needed repair for free or at a reduced cost as long as a great deal of time has not passed since your purchase. This approach is worth a shot...worst case is he says "hell NO"... Best case you save some money.

Good Luck....Happy Camping.
