Mom lives in Coffeyville KS where I've tried three approaches: (1) RV park spot rental; (2) 100% SOC charge, and; (3) commuting 20 miles to L2 charger. The RV spot rental ran about $20 a couple of years ago. But I need someone to pick me up and return me 2-3 hours later after the Tesla is charged. Given the high rental cost, it makes sense to maximize the SOC. Getting a 100% SOC at the nearest SuperChargers uses 1/3 of the charge to reach Coffeyville. This gives 1/3 for local errands but I have to leave with enough SOC to reach the SuperChargers. It is also costs about $11-12 to get a full charge. Driving between Coffeyville and the SuperChargers takes an hour each way, two hours lost before the additional charging time, 45-60 minutes. There is a free L2 charger, 25 mi/hr (30 A at 208 VAC,) about 20 miles away from Coffeyville. The charge time is just under two hours to handle commuting costs. So it makes sense to maximize the charge but at 25 mi/hr, this can take hours. The best approach appears to leave the house around midnight with a pillow and comforter. Park at the L2 charger, cat nap in car, and leave around dawn to return home with 220 miles minus 20 miles of the commute. It is the cheapest solution burning about the same commuting time and issues. Sad to say, the Coffeyville 1920s house power does not include grounded outlets. Otherwise, I could add 30-40 miles overnight using the portable L1 charger. If we can get a NEMA 14-50 safely added at the house, everything becomes much easier. But electricians are not cheap and I am an infrequent user. Bob Wilson
I forgot to mention staying at a motel and using the outdoor outlet on the ends of the motel. Again only 5-6 mi per hour, 30-40 miles per night and checkout. Bob Wilson
