Fuel Ecomony - Towing

2015 3/4 ton Chev Diesel - typically average 12-14 towing 5th wheel or gooseneck trailers. Usually a little better with the gooseneck as it is lighter and not as big as the 5th wheel camper. Not towing 18-20 on average. Mine is heavier than your trailer. The advantage to upgrading to a 3/4 ton or 1 ton is you have more options next time you upgrade the trailer. My only mistake was not buying a 1 ton from the start. My next truck will be a 1 ton. As for Diesel vs gas, I personally would not go back to gas.

If your decision what to buy relies on gas mileage, then you might think twice about the whole process. Gas mileage is not your friend once you start towing trailers. You have to pay to play...
