I've towed plenty of cars and trucks on a car trailer with a 4spdOD. Sure, not a motor home or such, but transmissions last if you treat them well. For example, you will hear people say how weak a T5 is . . . well I have rebuilt plenty of them and learned from the best, Bob Hanlon. If you mistreat them, they will break. But I have an '85 version that has never been apart. I have run 12.87 ETs, run a few parking lot races, been on the banks of Charlotte Motor Speedway with it, etc. So it depends on how you treat them, IMO.
