Thanks all for your responses and great comments. We have owned both aluminum and Fiberglas sides and in the end either works although it is easier to clean the Fiberglas. And, we have experienced the Fiberglas delamination which is a real pain if it has to be fixed. We had a new Alpenlite 5er that delaminated and it was taken back to the factory for about a month for the installation of complete new exterior walls.
It sounds as if none of you have needed warranty work, but do you know if a Forest River Dealer (more common on west coast) will repair the Palomino if needed?
Thanks for your input!
