I think I'd be afraid of that product line, but what I wanted to mention is Wheel Base. You need a good, long, wheelbase in a 31-ft class C to not allow the long rear overhang to:
1. Overload the Rear Axle, and/or
2. Under-load the Front Axle, leading to wandering/poor handling.
I believe one good thing about the Coachmen line is their wheelbase is at or over 220-inches. Our old Jayco is 218" which does a good job of load distribution, but we do not have a slide in our rear overhang.
Include a Truck Stop in your Test Drive, and weigh the coach on their scales. For $10 you can learn if it's well balanced. While you're there, make sure the Front Tires are 60-70 PSI and the four rears are equally inflated, to 75-80 PSI. THEN see how it drives. A Ford chassis can easily need more help with alignment and suspension enhancements, but it'll behave badly for sure if somebody aired the Front up to 80 PSI, let alone more.
