I keep changing my mind on things but I think I finally have it narrowed down between two vehicles. The first is the 2000-2003 Ford F250 7.3 powerstroke ext. cab. And the other is a 2003-2005 Chevy 1500 5.3 v8 gaser ext. cab. I know that with the powerstroke, I won't really have to worry about trailers that are too heavy or not having enough power. But yet any repair will be pretty pricy. And with the 1500 I don't have the towing capacity of a diesel (not that I really tow too heavy of loads right now) but the repairs should be much cheaper than a diesel. I just don't know if I want to lose the capacities by stepping down to a 1/2 ton truck.
