We just got home from a wonderful couple of days out on the road. I kept good good records of MPG. Our trip was a total of 605.7 miles towing, and we traveled 778.6 miles including site-seeing. The first 58 miles was down-hill almost the whole way from 6,000 ft down to 3,200 ft, but remember for all the down-hill time it is up-hill to get home.
We are towing a 2001 Scamp
19, w/ 14' tires
, behind a 4.3 lt 193hp, V-6 Chevy P/U
Our first fill up gave us 15.5mpg, after driving 291.3 miles.
Our second fill up gave us 15. 4mpg, and that was driving up and down small hills.
Our third fill up was to do some touring, we averaged 18.7mpg. This was climbing from 300ft of elvation to 3,700 ft, and back down to our camp ground.
Our last fill up was 14.6 mpg and we climbed from 300 ft of elvation to over 6,000 ft. were home is. Also there was a lot of up-hill and some down hill, in the 184.9 miles that we traveled.
After talking to others in the camp grounds, about milage, I have no complaints. We had a wonderful time, and I look forward to our next trip
