I started towing our Elite II with an F-150 gasser. I had enough power but was limited in payload capacity. Also, with a 1/2 ton pickup you have to use the weight distribution hitch, which can be a pain to put on at times. I needed to buy a newer truck a couple of seasons ago, due to mechanical issues with an older truck (not towing realted), so I now tow with a Silverado 2500 HD, 3/4 ton also running on gas. The benefits are not needing to use a weight distribution hitch, and an extra 1000 pounds of payload capacity. It's amaxzing how much gear you may want to carry. Add in 36 gallons of gas when weight is a consideration. Gas vs diesel is a personal choice. My Silverado is my daily driver, and it actually gets better gas mileage that my F-150 did.
