Fuel Mileage 2017 Ram 3500

9-12

About half that of what you get empty.

2014 3500 CTD CC SB 3:42 running in 5th gear 1400 miles 9800# 35 ft FW 13.5 mpg Mich to Houston. 60 mph or under. It reached 14 until I got on 59 south in Texarkana. 50,000 miles on truck. 23 mpg heading back with about 900# in bed.

Double towing 12,000 plus FW and 2,600 utility trailer I can pretty much get 10. about 24,500+ pounds total.

I averaged about 11 with a 12K high profile fiver.

Average with a 8500# (64 sqft frontal) bumper-pull over 13K miles has been about 10.9 mpg.
EDIT: I rarely tow over 65 mph (just to pass).

At the same speed and in the same climate & terrain I average 24-27-mpg solo, I also average 14-16 pulling my 35'.

Trailer aero and quality of WDH lash-up mean most, once past TV spec. Get it on the scale for the three pass analysis.

And, don't assume trailer axle alignment, brake drag and bearing pre-set are correct even on a brand new TT. Take it to a shop that specializes in big truck trailers. Or ask dealer where they send out mohos.

We need to buy fuel where Slowmover gets it, he gets 5 mpg better than the rest of us.

I've got a 2500 with 3.42 rear end and tow a 9500 lbs bumper pull. On flat land I can get around 12 (depending upon wind) towing at about 67-68 mph on the highway. Hilly terrain and I am closer to 10, same speeds.

Like they say, "Everythings bigger in TX. Even the MPG's are HUGE.
