Dually Ram Cummins, I'm guessing 17-19 empty depending on gearing and speed.

My guess with a big fiver 9-10.

2008 GMC 3500 DRW D/A puling a 14600 lb. fiver averages 8.5 to 10 mpg. Bobtail as my daily driver I'm averaging 16 mpg.

So, with my V10, I'm seeing about the same mpg as the diesels.....
Loaded. It's unloaded, where the difference is.

Only time I calculated it was heading to Goshen towing through the blue ridge mountains. I got about 13 mpg towing a full profile 2014 sabre 34REQS with a 2014 chevy duramax SRW 3500 crew cab long bed 4x4. The fiver is 40' long and weighs 12,380 loaded with a scaled pin weight of 2620 lbs. I would suspect that number to he higher towing on flat land.

Around town, no trailer I average 16 mpg. All fuel mpgs are hand calculated

Although I don't have a forty footer trailer, but during our recent move from California to Oregon. With our 98 Silverado 1 ton fully packed and our trailer fully packed, both overweight, we averaged about 8-9 mpg

Correct. Diesel is more expensive here.

Hand calculating is flawed if the truck does a fair bit of idling.

My display is off by 2 to 3 MPG's all of the time in my Ram. Also I will not allow my truck to idle except in heavy stop and go traffic. Idling is hard on an engine especially a new modern day diesel engine.

I am retired heavy equipment engineer who spent 40+years design BIG BOY Toys; so I do know a little bit about diesel engines and the working requirements of them.
