My 2014 Cummins SRW , I can get 19 to 20 miles per if I keep it at 64 or so miles an hour , manual measurement . When towing my 20 foot trailer at same speed I get 13 plus . I can go 450 miles towing if I carry a safety can of diesel, which I have never needed . Speed is the big killer of miles per .

"Speed is the big killer of miles per" Here is a perfect example! Towing 29K into a head wind heading West on I-40 crossing the panhandle of Texas.

Well there is your problem!!
You need to be turning 2,200 rpm to hold 75 MPH in a head wind! :S

Got to love the damn Tractor motor!!!! :B

Thanks for all the information. I've always been a Bow Tie man, but these new CTD are looking good. Just purchased a Jayco Jayflight 28BHBE and pulling it w/ a 2012 Suburban w/ towing package. It towed pretty good for the 35 mile ride home. No, to little sway, good, smooth acceleration and braking. Trailer sticker from dealer says 6911lbs, which includes AC and awning. We don't do dry camping, so just min weight for 4 people. The burb is due for tires in a little bit, so will be getting LT tires for better support. Lots of great info on here. Thanks for it all.

It is changing but for the most part I still have to travel further to find a station that is pumping diesel. I may have more range in theory with my diesel truck but that is offset by having to get fuel sooner to be sure I don't run out or have to make a 20 mile round trip detour to a truck stop.

Easiest to switch out the main fuel tank for a Titan that will hold 60 gallons of fuel and forget about it. For general driving the gas engine is the better choice. Diesel is good for trips of an hour or longer and when towing more than 10,000 lbs., otherwise it is not the way to go.

Not that that will prevent diesel owners from wanting to justify their purchase decision and pretend it was driven by logic and not emotion. I have a diesel pickup but I also have no illusions that it was the best buy or the most economical to own and operate.
