Have a 2017 Chevy 3500HD dually with 6.0 gas engine. Get 10 mpg towing a 5000# boat on secondary roads (60-70 mph). Get about 14.5 on same roads with no load. Get above 70 mph and it goes down considerably. Did get 18.5 on a stretch of interstate where speed limit was 60 mph in a construction area.
I figure with diesel about 40-50 cents a gallon more than regular gas around here, mileage is about a wash compared to diesel. I had a 2003 GMC Duramax dually and loved it but with labor cost so high now the maintenance costs were killing me. At about 12-14 years seals, gaskets, etc. start to leak. Was costing $600-$1000 to have a $150 part replaced.
My Chevy 2500 with the 6.0 gas motor. I bought it to pull 5er.
I took my first long trip and was disappointed in how it pulled the trailer. It was under powered and does not handle pulling a 12-14k # trailer.
I pulled the same trailer over the same route:
GM, 6.0 gas - 8.5-9.0 mpg
Dodge 3500 5.9 diesel and 6 speed manual - 15.7 mpg
Yeah, diesel fuel is a bit more expensive but I spend more more on fuel for my gas truck than I do on my do my diesel. Gas is 10% cheaper per gallon per gallon than diesel. However, diesel fuel contains 50% more energy than gas and gets more than a 50% boost in mpg
