About 35 miles freeway and 20 stop and go. Oo.:-laf
Love the truck so far. Still trying to figure out how to work everything.
Need to install wheel well liners and running boards, not to mention gauges.
BHolm said:My SRW 3500 Mega cab with an automatic and 3. 73 gears is up to about 16-17mpg on mostly slower 2 lane highway. This is with 12k miles on it. It started out closer to 14 mpg and has been slowly improving. My 2005 (identical powertrain) QC LB was running 17-18 after 30k miles and I expect that is about as good as it gets. I run Amsoil in the diffs and t-case as well as in the engine. Seems to contribute some to the milage.
