I installed the Big Wig anti sway bar and everything came in the package. Never had to remove the camper off the truck. If need be just take some of the weight off the suspension by lowering the camper jacks make sure to loosen the tie downs first.
Definitely the dually 4x4 with the manual 4x4 floor shift no automatic shift on the fly 4x4. Had a Ford work truck that had an auxiliary alternator for charging the extra batteries to power an inverter to run 110 volt tools. That would really charge ...
