Head wind ,and pretty much uphill the whole way from Camp Verde, Az. to Flagstaff, AZ, 6.8 MPG that's the lowest Iv'e had towing a fifth wheel. Then from Beaver ,UT to Salt Lake same trip was 11.9 , a bit of tailwind.

Next time leave TH on all the time along with full EB. Use cruise control to maintain your speeds by setting it and using the up and down to maintain the speed you actually want. While descending lock in the gear you would have came up in this will keep rpm's up and let the EB work well.
My 2015 Ram's EB will automatically downshift the transmission when needed.

Try running 35k combined down several miles of 6% grade without touching your brakes. Let me know if you needed to manually drop a gear or two to maintain your speed.
