Is the Enclave Front Wheel Drive (FWD) or All Wheel Drive (AWD)? That will make a big difference. In general, FWD can be towed with front wheels off the ground, AWD must have all 4 wheels off the ground, but that may be way too general a rule to apply in our modern times.
It would also be helpful to know the year model of the Enclave - then the owner's manual should tell you if it is something that can be done.
Some tow dollys have electric brakes and some have surge brakes. (Some have no brakes.) If your MH does not already have a trailer brake controller, the surge style brakes may be an easier route.
