I had a 89 v6 stdcab sb 5spd
on a uhaul heavy trailor I had me rig, nothin really heavy.
I left the bubs unlocked and when stop go stop go like in town I would use 4lo
it really sucked at take off, but I think you will be ok.
richardmud towed on a tow dolly the 89 stocker, 55 was ok and stopped decent
he towed it with a 91v6 runner
hope that helps
