Ram towing mileage
I had a 94 1500 standard cab with 360/automatic. Two wheel drive, 3.54 gears. Weighed 4600 lbs. Got 15.5-16 mpg on the interstate empty except for me. 13 or so around town. About ten hauling a car on an open trailer.
Bought a 2004 2500 Cummins/automatic four-wheel drive brand new December 03. Weighs 7,000 lbs. Gets over 20 mpg on the highway (22-23 if I take it easy), 18-19 around town, 17.5 pulling a car on an open car hauler, 12.5-13 pulling a 30 foot, 8500 pound travel trailer (except in West Virginia where pulling that trailer up and down mountains dropped mileage to ten-something).
I get better fuel mileage towing a car to a show than I can get driving the car.
Plus it tows so much more effortlessly than my old 360 did.
Will also pull a junk car out of a field, put it in four-low and just idle it out, don't even have to hit the gas (or maybe I should say the accelerator) - cars that gas pickups and diesel tractors couldn't even budge.
Will never go back to a gas truck.
