Phil4,
Unless you drive 200 miles a day you won't need two chargers. I have a 14-50 with a 60AMP breaker that gives me 40AMP on the GEN 1 Mobile charger, and a 6-50 on a 40AMP breaker that gives me 32AMP on the GEN 2 mobile charger.
I have 3 Teslas now and I haven't had the need to use both chargers at the same time yet. I mostly did the two outlets for the convenience of not having to move the cars to be able to charge.
