He's moved the loads around a little but considering what he carries, its so minimal considering the overall weight. The biggest thing is he has carried his Harley in the back and without with no real difference in ride.
Not sure about his rear suspension.
He does have aftermarket air bags. On the long trip from Tn., he tried everything from 5 psi to 100 psi. No real change.
We're really stumped as to which way is best to go. Obviously, he doesn't want to get rid of either truck or camper. But in all reality, one has probably got to be changed. Then that question comes to: which one?
If he changes campers to a lighter one, will it fix the problem? If not, he has given up his dream toy hauler for no reason. If he changes trucks, in all reality the problem will be solved because he'll get a dually and the Sidewinder will be replaced with the standard OEM hitch the Momentum came with. But he's spent a bunch of money to do so.
