Fuel mileage 2017 gas trucks

2015, Ram 3500, SRW, 4x4, short bed, mega cab, 6.4 gas. With 5000 lbs of extra weight from camper and goodies it gets 8.5-10.5 mpg. Empty 13-15 mpg. With the massive amount of torque and HP of the new diesel trucks you cannot make the diesel pay for itself due to increase in fuel economy, and if al you plan to do is haul a slide in camper the gasser is more than enough to get the job done. With that said, when you are running up long steep mountain grades be prepared for that gasser to gear down and the rpms to come up to 3500-5000 rpm to maintain speed.

We have a 2016 and a 2017 F-250 4x4 regular cab 6.2L pickups.

12 mpg empty on the freeway and 7-8 towing.

2017 F-250, 6.2, 3.73 gear 4x4. No exaggerated fish story here... about 10.5 mpg unloaded driving around town, 15 mpg highway if I keep it under 60 mph and 8 ish (and as crappy as 5.5) pulling 7,500 lbs.

2016 F250 V8 6.2Ltr
I get 16 highway, no load, 12 highway small trailer, 8 mpg with 10,000 trailer. You pay to pull.

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

Asking about fuel milage is a bit like asking how big the fish someone caught is. The truth is it depends on so many factors that the numbers can be all over the place. How fast are you driving, plains or mountains, wind, etc.

As a data point, on reasonable flat ground driving on the freeway at 68 mph with no wind I will average 9.0 mpg with my camper. Give me a strong headwind - 6.8 mpg. Give me a strong tailwind I can get up to 12.0. Drop the speed, milage goes up pretty significantly, raise the speed, it goes down fast

2013 F350 CC DRW, 6.2, DRW 4.3 axel. AF1150 camper. Entire rig loaded up is just under 14,000 pounds

I can get 22.5 to 23+ mpg driving conservatively on flat terrain in my new Silverado 4x4. Eleven to almost 13 pulling my 5,200 pound Winnebago TT. 5.3 Liter with "Dynamic Fuel Management." Whatever that means.
