My QC LB dually was my only vehicle for 9 years and the only reason I got the Jeep was to go to the desert and mtn trails and to keep the miles off truck. For you, I think it's a toss-up as long as a srw will comfortably handle the weight AND payload. In my experience, the diesel premium was completely paid back at the time I sold them.
Old truckers, like me, used to base the necessity for diesel on how many miles driven and it was 2000 miles/month, not 2000 miles/year. I went from a gas to a diesel TV when we started RVing and driving a LOT. We camp in the mtns. and the exh brake is awesome but I'd have no problem going back to gas for your use.
I would favor diesel more if the new ones were as reliable as the older ones but all the electronics alone scare the bageezers out of me and my luck with anything that has a lot of electronics, sucks! Craig
