my mj was flat towed by a full size dodge with tailor breaks on the way back the full size dodge was towed by my mj breaking wasn't half as bad as looking at the sky and a very light steering wheel it can be done but don't do it with your $500 tires on go get some good street tires and beef up the rear suspension and bigger disks and disks all the way around and if the tranny doesn't crap out half way there you'll be ok.
ps my bumper had a nice bend in it when all was said and done
