Gary Swanson – Tried your web address for photos and was greeted with the Amazon login screen. Guess I will have to create a user I.D. and password to get past that welcome screen.
As for the mileage, I was rather proud of that result as well. I keep a diary and a mileage/maintenance record. Part of the high mileage figure is because of a nice tail wind several times and dropping from an elevation of 5,000’ + to just over 900’. Also had very cool and a little humid weather - no air conditioner load. Had a 700-mile segment that we got over 15mpg. I do usually run about 5 mph below the speed limit – trying to not hold up traffic, but slow enough to do some relaxing sight seeing. The 5.7 might be a little more fuel-efficient than the 6.0, but lacks some of the power. I normally expect mileage to be 11.5 to 12.
Cheese1 – Welcome back, what did you think of cold weather camping? We drove fully winterized meaning empty tanks. That helped the mileage as well. Carried a gallon milk jug sitting in the sink for hand washing and one in the bathroom for emergency flushes. Liked the quiet ride with no A/C or open windows. We were impressed how the cab heat on low fan speed warmed the coach to a pleasant 70 degrees when the outdoors was in the teens.
