I always find this topic interesting. As a general rule a Class A will ride better than a C, and a DP will ride better than a gasser. But there are so many variables and opinions that the only real option is to drive a few yourself. What one man might think rides rough could be another man's dream. It's objective. Also it really depends on how any particular unit is set up, loaded, psi etc. As an example, our first ACE rode a little rough, our second rides much smoother, impressive actually for an entry level A. The only difference is the tires. The old one had Conti's, the new GY's. So it can really come down to very different things. Also, I wouldn't pick a model based on ride alone. Pick a floorplan, find models in your range that have that, and drive them. Then decide if you like the ride. But I think it's impossible to simply say, x brand rides better in this range. You have to feel that out, pardon the pun.
