Hi Jim, We have a 2012 Puma 30FQSS. Love it. Have never had a problem with it. Never had to take it back to the dealer for any repairs or touch-ups. It is a solid unit. We live in a Puma rich environment. Lots of folks around our area have them. All the owners I've talked to had no complaints about the Puma brand. I'd buy another without hesitation. As far as the difference between aluminum and fiberglass siding mentioned above, it's a matter of personal taste. Assuming you purchase from a good dealer, I don't think you'll go wrong buying a Puma.
