I know there is lots of chatter on the best way to manage the run from Rapid City to Sheridan. I made it straight through at the end of July. The key is the speed. I charged to 274 and then set out. I set the cruise at 65 and did not budge. My avg Wh/mi was 285 and we arrived with 30 miles remaining charge. I was driving an 85D with 19" cyclones. The temp was upper 80's and there was probably a 10-15 mph cross-wind. I hope this helps for anyone considering making the run. P.S. The return trip is a bit easier. I set it for 65 again and was able to take it up to 70 for the last 65 miles and still finished with 33 charge left. My final Wh/mi was an amazing 265. In addition, it was probably 98 degrees on the return trip.
