For 4 wheels off the ground car hauler I like U-Haul...very heavy duty unit...it weighs 1900 lbs...I like the way it has straps that go over the front tires and ratchets to tighten...I used that to trailer my "T" to Vegas last year...
i'm in the same boat...looking for a flatbed trailor to rent to haul my GN to the new house we are getting...will be towed with my 99 ford f-150 5.4L v8 4x4
