I would heed the advise of those who are hauling the bigger units. Especially the tongue weight.
My 25 ft. TT is advertised at 5000 lbs. and 400 lbs. on the tongue. Loaded for the road the CAT scales shows it weights 6200 lbs. and has a tongue weight of 750 lbs.
My F-150 can pull 9500 lbs. however the max cargo posted on the door jamb is 1411 lbs. So with 750 lbs. on the hitch we only have 661 lbs. for people, dog and camp gear in the bed.
Know the real numbers before you buy, particularly the max cargo of your tow vehicle.
Good Luck
