We have a 2012 GMC D/A crewcab combo with a short bed 4X4 and just finished a trip of about 600 miles, about 350 towing a FW, Jayco HT 26.5 RLS and a 19' Crestliner Superhawk in the mountains here in Wyoming up to Grand Teton. Total overall mileage, hand-calculated was 13.8. On the highway driving around 70 unloaded we get between 18 and 19 MPG. One thing with the D/A combo is that I never have to worry whether I have enough power to pull the load. Gas engines will inherently get a little better mileage unloaded and less when loaded. I think it's up to you whether you would like a diesel since it takes a lot of towing and unloaded highway miles to "pay" for your diesel premium of around $8,000. When I traded out of my old 2003 diesel I toyed with the idea of buying gas, but decided that I would stick with diesel due to the size and weight of my FW and boat. My FW is a light one, probably 8,500 loaded and the boat is around 3,500 for a total towed weight os about 12,000. Certainly nothing a good gas engine can't handle, but at what price for fuel and wear and tear on the engine? I don't know the answers and don't research this situation extensively, but I don't plan on getting rid of my GMC until I get rid of my FW.
Good points, and you mentioned at what price for fueld and wear and tear on the engine. That is good to think about, since I'll be on the flip side of that, not towing much at all.
