We had our annual family "camping" trip, this last weekend. First time Moby with a brain(UltraGauge) that communicated. Down from VirginiaCity(6000'asl) to Reno(4478'asl) to Stampede Res(5954'asl) and back. 55-60mph on the Interstates, 35-40mph on the paved 2 lanes.
Averaged 8.36 MPG. Sure was fun watching the InstMPG- 999.9 when coasting downhill. Moby ran great.

Looks like I'm doing better than most, who're likely pushing along at 70mph.
I really have to keep a lookout at the rearend overhang, behind the "short 208in" wheelbase of the RV. Adding 2+ feet to the rear, that I can't see in the mirrors has me a bit worried.
