I'll keep it simple on two points: 1) storage and 2) are you going to tow?
We almost purchased a Class A going from a 32' TT. After DH asked me where I was going to put the garbage can, I began looking around. Not much storage.
We were going to take the first few trips without a toad due to the cost involved in the setup. Another thing to take into consideration.
In addition,when we took the test drive, it really rolled and I get car sick easily. DH said we can solve that with sway bars, which will probably fix your problem when semi's pass.
