My wife & I have done a few road trips in our Tesla now. We bring our two small dogs, so we would be stopping every couple hours for 15-20 minute breaks anyway to let them walk around a bit & pee.
The last trip we took just last month we stayed in 3 different AirBnBs. The first one had a free to use level 2 charger in its garage. The second one was across the street from a municipal lot with free level 2 chargers. The third one was the only one that required our use of SuperChargers every few days. So 2/3 of our trip we had free charging.
Airbnb appears to be encouraging renters to install EV chargers if they can. It’s a nice perk for those of us looking for them.
