Maybe try a 2000 and up Ford F-150. My grandfather has one with the crew cab and short box and has gotten a lot of use out of it for the farm/house/and other things he hauls with it. It's got the 5.4 gas motor and those motors are common enough to the point that you could get aftermarket upgrades or replacement parts really easy and cheap. What sucks about it though is that it's only getting like 12-15 mpg per tank. Hence, why I think diesel is so much better.
