If you are using the UMC at home, I'd recommend getting another for the car. Relatively cheap insurance. There's always the possibility that something out of the ordinary occurs and she need more from the car. I use mine when parked at the airport and when parked on trips. Sure, I could use one, but it is always nicer to not to have to remember things.
You definitely need to take a weekend trip, or something to extend the range. In our 88 mile Leaf, we took what was about a 65 mile trip. We made it there. But had an broken DC Fast Charger and the J-1772 were ICE'd. While we had some other options, going to them would take us very close to 0. So we finagled the cord around and got plugged in. Got charged and made it back home. The little town of Clayton Georgia is a mountain town and a great place to chill for the time it took us to charge on the J-1772.
In other words, Plan A failed, Plan B failed, but we got back home and had a quite enjoyable adventure doing it.
All along, we knew, that at an absolute minimum, we had 120V charging available and we'd have to stay overnight.
That went a long way at defeating range anxiety and was a great adventure.
But in this case, the Model 3 LR tends to suck. It takes a 4 hour drive to run that damn thing down to near 0, makes for a really long trip.
18,000 miles in less than a year. From Atlanta to Ft Lauderdale, From Atlanta to Jackson MS to Destin FL and back. Multiple trips to Knoxville TN. Trip from Atlanta to Dayton Oh coming up next month. Been back to Clayton on roads that many Jeeps wouldn't go, driving around, looking at houses all day and back to Atlanta on a single charge.
