I have a 2005 Coachmen Cascade.. it is fiberglass sided.. this model had the option of aluminum or fiberglass when new... 650 more for fiberglass..
and this must be the reason my 7500 pound trailer is 8300 pounds... Empty.
beside the 2 30 pound tanks, battery... etc.
the logos and strips are all cracked/faded.. but the siding is still very white.. just some/most of the shine is gone.. I hope to wax it soon. and see if some of the shine will return.
I do like the flat sided look of the fiberglass. and the wife loves the Front Kitchen... 29FKCS. aka counter space. and room to move around.
