My only issue with any routing is dependent upon what happens at the border. While not a bad plan to charge before going across the border, if you get stuck in an hour or more worth of border traffic, you might have to do a little creative replanning. Thankfully there are options on both sides - probably because of border traffic.
I'll say that there's a lot more options than when I first made trips along this way back in 2016 - it's opened up options as opposed to strictly keeping to one route (and almost running out of battery along the way). Note: add more charge than required as it's hilly and if you combine that with weather, it can be close.
Also have some secondary charging apps - ChargePoint, Plugshare, ChargeHub in case you need to use alternate chargers at your destination or along route.
