Towing MPG Thread

WITH MY TRUCK AND A FULL SIZE CAMPER I GET 17 MPG'S

Back to the top, I towed a 23' enclosed trailer loaded fairly heavily at about 70 MPH on semi flat hills to rolling terrain about 3 weeks ago. Would guess trailer and load weighed about 6500 for a combined 12500. Went about 350 miles with it. Got 10.7 MPG. This is with my '98 12V auto, 3.54 gears, 2-wheel drive short bed, TC locked up at least 95% of the time. What do you think. . . that MPG doesn't seem to be that great compared with what you guys are seeing.

We Canucks have big fat 4.54 litre gallons. US gallons are about 3.79 litres. My truck gets 19miles per Imperial gallon towing my 26.5 foot fifth wheel at 100 kph (60 mph). Empty it gets close to 30 mpg at a slightly faster speed. Hills and crosswinds eat into my towing mileage as has the ultra lo sulphur diesel. I swapped a 410 for a 354 gear set and found it gave me better mileage although I now use first gear to launch when pulling. After converting the rear end, I did not like the increased gap between the gears. The 3200 gov spring fixed that problem.
