We had a 2007 Cherokee 29B (quad bunks) for 7 years (Now they are Grey Wolf). We really enjoyed it. My two biggest worries were, 1) when is the hail going to hit, and 2) when will I see my first rotted board. My trailer was all wood frame, light, and low profile. I have had a window leak from a warranty replacement that I didn't notice for a couple years and just recently had the hail and am upgrading. It held up to a lot of kids banging around on the inside and survived well! That said I have been inside the Grey Wolf and they seem to be built OK. I believe they are still wood framed but can be ordered with the fiberglass sides. Seems like the price is right and will be a great upgrade from a pop-up.
I upgraded for the aluminum frame and fiberglass sides. That is just me.
