With the price of fuel I thought it would be interesting to see what other people are getting with their truck and camper combinations.
I have a 2009 Dodge 2500 4 door 4x4 short bed with a Cummins 6.7 liter diesel, 34” Toyo Open Country tires and a Carli starter kit suspension with their long travel air bags. For my camper I have a loaded Hallmark UTE . Total weight of the pair is about 11,400 pounds (yes I know I am over the truck’s GVW). I run the tires at 46 in the front and 64 in the rear based on the Toyo load chart (wear is even after 20K miles). On my recent 1,600 mile trip to the Overland Expo from the Bay Area I averaged a disappointing 11.8 MPG going the speed limit which was generally 65 to 70 mph.
Obviously shedding weight and driving slower would help. Does anyone have any experience running the tires higher or using the economy setting on a programmer?
