We're just wrapping up a roadtrip across the US, from Vermont to Arizona. I'm sure you won't be surprised to hear that the Model 3 is an excellent roadtrip car. We mostly charged at Superchargers (17 in all), but occasionally got a charge on a 50-amp campground plug overnight, or at a friend's house. Here's the stats: Superchargers visited: 17 Total Supercharging cost: $99.48 (from Utica NY to Page AZ) Total miles: 3,506 (we didn't go the shortest possible route) Cost per mile: 2.8 cents Total kWh used: 723 Wh/mile: 206 I'm particularly impressed with the low Wh/mile consumption. That comes out to full-charge range of 360+ miles, allowing us to charge to 80% or 90% and skip many Superchargers along the way. The numbers don't show what a pleasure it was to drive the car, even on days when we covered more than 400 miles. We used the TT30 adapter from EVSEadapters for campgrounds that didn't have 50-amp plugs, and it came in very handy. We used it as often as the 50-amp adapter that comes with the Mobile Connector. I highly recommend this adapter if you camp occasionally. Stopping for a charge had little or no impact our travel time. For short stops we typically charged from 50% to 80%, which takes about as long as a bathroom stop and a quick walk to stretch the legs. Once a day we'd do a longer charge while we had lunch, for about 45 minutes. We never made more than 2 Supercharger stops a day. Bottom line: it was easier and cheaper than I expected to drive the Model 3 across the country!
