We had a Shadow Cruiser pop up for a time and hauled it on a long bed truck. Single rear wheels tho. No adjustments needed. The front jack and the single side will need extended if you're running a dually. A heavy duty "I" beam to match up with jack brackets type extender would work as my son in law made a set for the front two on the hard side Shadow Cruiser we now have on an 04 Chevy Duramax 3500 DRW. Standard corner brackets wouldn't work on our new old camper especially on the water heater corner, no room. We take them and the jacks, front and rear, off traveling as we don't take the camper of at camp sites. Either the Torklift or Happijacks will work, that's just personal preference and pocketbook decision. We're using HJs and are well satisfied but others not so much as the bumpers on the new trucks aren't as strong without added braces. Love hearing about folks with the old Shadow cruisers!
