Your recommendations, please. I potentially need a used, quad style, gasoline fueled pick-up truck that will pull a 6000 lb loaded airstream trailer, and carry a 1500-2000 lb payload capacity. As I will use the pickup for possibly 18,000 miles of independent driving and 2000 miles of towing per year (20, 000 miles total), I want to find the most fuel efficient “beast” possible. Of course, I also want it to tow well. Short bed vs. long bed? Four wheel vs. two wheel rear drive? Please, provide rationale for Chev. vs. Ford, Dodge, etc.

 

Long-bed Power Stroke. Hands down.

the longer the wheelbase the less sway when towing. you need a 2500 series truck.

diesels are 30-40% more efficient but the cost to maintain or repair an old diesel is crazy. if your towing primarily go diesel, if not gas.
cummins is my choice for a diesel. Do not buy any high mileage diesel or you will spend a fortune replacing injectors or worse...headgaskets. ford and lesser so gm diesels are hard to work on imo.
5.7 hemi for a gasser. if you gotta go gm 2000 to 2006 2500hd 6.0L 4l80e for a gm gasser
