Ok, so I just want to see if I'm on with my MPG or low or what. Sig says what the truck has, I am pulling a 40' 5er, dual slide outs, gross weight at 22,500. I was averaging 10-11 mpg, 850-1050 egt, 180-190 trans, 200 coolant, pulling at average 60 mph at 1900rpm. I am also using fuel from on Ft Lewis with 5% biofuel. Pulling in the Northwest Washington, south of Olympic Forest, Air temp approx. 55. Any feedback would be great. Thanks.
