Yea, I know, just had some real bad experiences with diesel in the past, the possibility getting gelled up on the side of the road countless times just doesn't trip my trigger any more. The newer rigs must have tank, fuel line heaters, more to go wrong! I would buy a Ford 1 ton with a 460 gasser single rear wheel, that way you won't throw a rock through your camper, if you have been off road and not checked your tires and got a rock stuck in-between the dually's, if I was going to pull a heavy load occasionally. Whisper quiet and no smoke. Other wise I would buy a semi with brakes large enough to stop if the camper brakes failed.
