I don't know your soil composition but best idea is a broad concrete driveway reinforced with rebar. The bigger the surface spreads the considerable load out. Your Mh might be 28,000 to 60,000 lbs.
Another alternative would be about foot deep of 1 3/4 stone packed and the new mim that is far better than crush and run and then on top of that big thick pavers all properly compacted. Won't crack and provides a pleasing surface, but if need be pavers can be replaced or removed and reset.
You soild may not need such. Local Paving Contractors are the best consultants but not the ones who just want to pave a drive way with one year guarantee.
