My mh is a 33 foot class a. It has the generator in the rear and is very sturdy in the back with the generator mounts and all. I pull my 28 foot trailer that is right at 9200 pounds with no issues. I just stop at truck stops when I get fuel. All the Flying J's have a dump station and rv pumps. In the owners manual of mine it says that you can pull 8430 pounds with it.
I would recomend one with the Generator in the back because it makes it beefier back there. My Uncle has the same exact mh as mine but 2 years newer and he pulls a 32 foot tri axle with 2 cars and a golf cart. It pulls it great and he hasnt done anything to brace his hitch.
A friend of mine bought a 38 footer with the tag axle and he regrets it. It eats up the tag tires with the wieght of the trailer back there. My dad had a 25 foot class c (van nose) that cracked in the back from the stress of the trailer. But it had the entry door clear at the back and that weakened it.
Here is a picture of my setup.
