Visited on July 28 without charging.
Every sign for this rest stop along the freeway has the EV symbol.
At the car/truck fork at the entrance to the rest stop, there's a gas pump and EV symbol for both sides, but I didn't see any charging station in the truck area on this side. This seems to be a mistake, as if you drive to the truck side you can't come back to the car side where the chargers are. I was wondering if there was a way to drive to the other side and use the dedicated truck charger that's available for direction north, but the maps and satellite images don't seem to show this is possible.
This is one of the rare places where every single connector on a 6in1 EVTEC charger can be used at once, as there are 6 charging spots to accommodate the 4 DC (5 with CHAdeMO, but one is mutually exclusive with the CCS) and 2 AC.
The 2 parking spaces for the 300kW+ unit are not next to each other, so it might not be immediately obvious if the pair is already in use. You probably want to use the 300kW+ charger in any case, because the older charger is only 120 or 150kW. The old charger has no power indicated on it, but the newer charger has the maximum 384kW rated power written on it. GOFAST usually lists it as 300kW in the apps.
