You've heard about the Sun Country, Roadster Network, etc. Mentioned already, but very important is the fact that Tesla is putting in multiple 80 Amp HPWC's at most of their showrooms (usually in a nice mall) and service centers. On top of that they are offering incentives to hotels that install HPWC's; I think the incentives should be larger, but that is up to Tesla.
Here is another obscure reason to have dual chargers and be able to use High Ampere L2 J1772 EVSE's (HAL2). The first Pacific to Atlantic Supercharger route is following a rather circuitous, but very scenic route across that U.S. Because the original roll out of the Supercharger network left a big hole in the 4-Corners of the SW US, I started the
4 Corners EV Charging project.
Now the Elon route is coming to our back door. If you have dual chargers, there is very nice alternative to the Elon Route. You can take the Supercharger route from Farmington to Silverthorne,
Farmington, NM to Silverthorne, CO via SuperChargers - Google Maps, or you can take the 4-Corners EV route through Pagosa Springs and Salida,
Farmington, NM to Silverthorne, CO via HAL2's in Pagosa and Salida - Google Maps.
With dual chargers, its a toss up for total travel time. For those trying this route, I recommend doing one path each direction. Moab and Glenwood Canyon are pretty nice, but so are two extra crossing of the divide (Wolf Creek and Fremont Passes), as well as seeing some great back roads, high alpine, Colorado. If you spend the night at
Incredible Pagosa and do a range charge there while you have a nice dinner in town and grab a soak in the hot springs (maybe even stay a few days and grab some skiing at Wolf Creek), its even faster going the Pagosa/Salida route.
