Just bought a TT and don't have a TV for it yet. One friend, who tows a lot of heavy things, recommends nothing less than 3/4 ton P/U. A mechanic friend, who we will be camping with, says his 1/2 to...
I Belong to the Tim Taylor school of tow vehicles "MORE POWER, MORE POWER"
Seriously... If you go with the larger truck, you will find the ride is better, and the tow is easier.. If you go with the smaller truck, Well, you may be ok but you will always wonder
And if you do not want to EVER ask "Can my truck tow this"
