Rear Wall

[cw3jason]

I have a question about the new 2015 Montanas. When I inspected the trailer I noticed the rear wall seemed different than the sides. I do not have the Legacy package so no rear fiberglass cap. The sides are solid rolled fiberglass over 2 layers of Luan paneling and feel solid. The rear wall seems to be a different material. More plastic like and does not have the same texture. When I press on it it has some give. It does not feel voided or delaminated, just different. Is there something wrong with my wall or is this normal. Hope ng other members can tell me about their walls.

Thanks
Jason
