With a curb weight of 3,328 lbs, and add a tank of fuel and the usual junk folks keep in the car, you are looking at 3,500 lbs more or less. That's pretty heavy.
Into the bargain, if we assume you want to be able to drag that rig through all of the North American states, your toy hauler can't be more than 96 inches wide, to contain that 69.1 inch wide Jeep That leaves you 26.9 inches clearance, call it 13.4 inches on each side -- good luck opening the door to get out once you've driven aboard, and that's not allowing for any thickness to the side walls of the toy hauler.
Just between you and me, I think a better bet would be to drag that Jeep 4 down. But good luck finding what you want.
