I am on MH #2 on a Ford Chassis. Total mileage is around 50,000 in 8 years. The first rig was an Itasca 33k, Rig 2 is a 35J. All I have done is verify I am under the max load, (Considerably under) I've never approached 'Full' and that would be with a total of 4 230 pound adults and a bus load of gear. The only thing I have added is to change the links on the front sway bar.
Noise can be an issue. Sitting on top of the engine is a bot loud. Speed can mitigate a lot of this. You really don't need to be doing 75!. Much quieter at 58-62 and better mileage as well. Some road surfaces are definitely loud!
Handling is not bad, Obviously again a winding rolling country road is far different in a MH, any MH than it would be in a car. I occasionally get pushed around by a truck, most pass without notice. Power has been more than adequate. I have added a 5-Star engine tune.
