As others have posted, 120 V is not good for 66-70 miles per day. You could:
1) use a dryer outlet. Purchasing a Tesla 10-30 or 14-30 UMC adapter, and probably a 240 V 30 A extension cord, will be required
2) install a lower current 240 V outlet to save money. With 240 a Volts, even a 12 A 6-15 outlet would be enough. Just change the circuit breaker and the outlet from 120 to 240 V. If the wiring is good for 20 A, then a 16 A 6-20 outlet would be a great solution. Adapters, both Tesla and third party, will be needed.
3) install a 24 A 10-30 or 14-30 outlet, and get the appropriate adapter from Tesla.
4) install a 120 V, 16 A 5-20 outlet to get maybe 5 mph. You need to get the Tesla adapter. I don't recomend this, it is too marginal for 66-70 mi/day. You need some sort of 240 V solution.
