One thing not touched on is having it weighed and adjusting the tire pressures according to the loaded weight. When we first bought it ours new ( never drove a MH before) it was a challenge taming it going down the road. The tire pressures were way high according to the loaded weight charts ( from tire manufacture). After letting air out per axle weights it solved that problem.
If you don't it will wear you out mentally and physically. Don't oversteer, make minor corrections waiting for the MH to adjust. If you try to force quick corrections you'll find yourself soon correcting back the other way.
