I'm always leery of people saying "I can tow XXXXX# and want a bunkhouse." The more important number is payload. Family and gear add up fast.
We had a North Trail and currently have a Grand Design. I didn't like the wide track axles on the NT, too much tire side scuffing on tight turns. Had NO major issues with it and had an exemplary dealer to back it up. But it wasn't as nicely finished as the current GD and we love GD's floor plan.
But the GD has had (and still has) a few problems. Total of 33 days in the shop and it's still not fixed. The problems aren't that major, I lay the blame squarely on the dealer and their service dept. I'd still buy another GD, but not from that dealer.
