I have a diesel for the fact that i tow my 7 ton trailer with the skid steer. Other than that, a gas job would be fine to tow the maintenance trailer around. Another thing is if you do a lot of maintenance, the constant star, stop, start, stop of a diesel can shorten the injector and starter life greatly. I'm looking to buy another truck and I'm shootin for an F-350 with the V10. If you plan on putting a dump insert get the V10 as well, the Ford Triton V8 has NO balls with certain loads.
