Thanks for posting the pictures Jeff.
I thought I'd share a brief trip report. Truck miles from Chicago area to Lake Powell then San Diego and back were 4,874. We averaged 11.2 mpg towing (lowest was 8.1 and highest was 14.6). Boat miles came in right at 200. We spent 6 nights aboard on the hook or beached.
Lake Powell is spectacular! This was our second trip there with the Mokee Dugway. I'd go again in a heartbeat.
Yes, the A/C was much appreciated as daytime temps were in the upper 90's, and the nights didn't seem much cooler.
