So my boss wants to drive his S 60 from Seattle to Pullman. After the supercharger in Ellensburg it's 192 miles to Pullman, which is cutting it close. Does anyone know of any level 2 chargers in Othello, Royal City, or Colfax? Just 20 minutes at a 240V - 30A would probably give sufficient buffer to make the trip.
It's a charging wasteland out there. RV parks are his best bet. There is one in Dayton that has had a few Tesla's charge there.
On the plus side, it is very flat out there once he gets over Rye Grass Hill, so if he does a range charge and keeps it at 55 he should be able to pull it off in one shot.
A little ways east of Royal City there is a golf course that has RV spots but I don't know if they have 14-50s. I think it is at Dodson Road. It is the Royal City public golf course and RV park on Dodson Road.
There are several options at Moses Lake on I90. Plugshare B your friend. I know it's a bit out of the way but it's only 132 miles from ML to Pullman. And on I90 you can drive faster...
