You don't really need a full ton dually when you go to buy a used motor and end up with two 'cause the guy took your ridiculous offer...
You probably don't need a full ton dually to haul the car to the track, but it does make it a pleasant drive. And it really doesn't care about going down and up the mountain to get there and back...
You definitely want a full ton dually for the traveling roadshow...
It was probably overkill for hauling 5 35x12.50s for the Bronco home from Discount tire the other day, but who cares. 28,000 miles on the big rig at this point, ~21,000 of that with the camper in the bed, a trailer hooked up, or both...
Speaking of Broncos... do they count as truck (ish) stuff?
