Just finished the trip, loads of fun. MPG was 12-13 @ 70 MPH. Got to drive a 02 PSD, see Garden of the Gods, Devils Tower, State 14 to Yellowstone, drive through a winter storm, saw temps of 19F, froze water pipes inside the TT, Grand Tetons, it went by so fast. Didnt get to drive on Wy State Rd 16 because of snow, and didnt get to drop in on WyoJim
. Truck was fine except for 1st gear
Got the exhaust brake installed 2 days before we left, definately a good investment, and it sure save me on the ice
