Just arrived home yesterday, October 9th. The trip went really well and the Pmaster performed admirably. I did have an occasional false tire pressure warning but other than that, all was good. This was a really high altitude trip with Yellowstone, Cody, Wy, Rocky Mountain National park, Devils Canyon and Bannock, Montana. Most of the trip was above 6,ooo ft elevation with as high as 12,000 in Rocky Mountain NP. Fuel Mileage was 19 MPG on the nose for the 3500 miles. I couldn't have asked for better. Montana, Wyoming and Colorado all sell 95 octane regular so I tried it and had no pinging at all even at those altitudes with the grades I had to climb. I used a small 1200 watt heater at electric spaces with an outlet thermostat to regulate the in van temperature for sleeping. Worked very well! Now to do some tweaking to some of the storage to make it a little more accessible, but all in all....it went great!
