+1. If you only opt for a 50-amp service, make sure to specify copper wire; otherwise aluminum wire may be installed. FWIW in MN, aluminum wire is limited to 32 amps / 40 amps breaker when snaking through insulation.Were I him, I'd probably put a 100-amp run to the garage, terminating in a pair of NEMA 14-50 outlets. That gives flexibility with the 14-50 (suitable for a pair of 40-amp EVSE like the JuiceBox), or could handle an 80A single EVSE.
Ideally would be a pair of 100A runs, but that's going to cost more breaker space and would be overkill for all but the most demanding cases.
