We are on our way to our daughters in ID. This is the first trip with this coach that I have not been pulling a 12,000# trailer or our Avalanche. I am amazed at how nimble it feels. It was a perfect day with temps from the mid 70's to upper 80's. Winds mostly light and variable except moderate tail wind the last 100 miles into Fargo, but became a side wind after Fargo becoming a strong head wind the last 30 miles into Jamestown, ND. 525 miles total and I averaged 9.3 mpg with the cruise set at 64. This is from my VMspc that I have calibrated to match miles driven divided by gallons used over several thousand miles. With the trailer, I could do 7.3 mpg if wind wasn't a factor. Not sure with the Avalanche, as I have not taken it on a trip with this MH, but probably around 8. I'm pretty pleased with today's run. I'll see what the next two bring.
