We had an 02 Limited w/ V8. As said if the 4WD had 2 shift levers on the floor with the transfer case having a positive Neutral you can tow it. Just shift it to N and then put the tranny in D or R and if it doesn't do anything you're good to go. Put the tranny in P and the key in the Aux position. Next to our 1st toad, a 91 Honda Accord 5spd. it was the easiest to hook up and go.
Just remember the GC is heavy especially the limited, 5000lb.+ and you're driving a fairly large Gas coach. You will definitely need an auxiliary braking system for it.
I've said all the good things I know about the GC.
Good luck on your adventure
