Miles/kwh results?

What experiences you have on the efficiency (not range although they are related).

Low speed, towing, highway etc

Towing my travel trailer at 55mph:
378 miles, 296 kWh, ~1.28 mi/kWh
Averaged 1.2 mi/kWh going uphill, 1.34 mi/kWh going downhill
Route: Colesville, MD to Coopers Rock State Forest, WV and back. ~1700' elevation change.


Trailer: No Boundaries 19.8
Length 23'8"
Width 8'
Height 9'6"
UVW 3,789 lbs.

Reading this thread today.. Yesterday I drove 50 miles each way (100 mile round trip) and averaged 2.1 miles per kwh using cruise control at 74mph (negligible elevation change) and air temperature of ~45-50 degrees. Are highway numbers that much improved during the summer months or are the battery packs providing inconsistent results?
Results are very consistent from vehicle to vehicle under the same conditions. Warmer temperatures will increase efficiency, as will slower speed.

Updating this for our 10,000 mile trip towing the trailer across the county and back January through March:

Average efficiencies of
60 mph: 0.94 mpk
55 mph: 1.09 mpk
50 mph: 1.26 mpk

If you want more range, slow down!
