Here r the facts 50 amp service is just that there is a total available power of P= VxI or 120 volts at 50 total amps = 6000 Watts not 12000 Watts. With 50 amp service you have two mutually Independant 120 volt legs one rated at 30 amps the other leg is rated st 20 amps. Therefore the following P1=(30 x 120) = 3600 watts plus P2 = 20 amps x 120 volts = 2400 Watts. Ptotal = P1 + P2 = 3600 + 2400 = 6000 Watts.

50 AMP service is 30 AMP plus 20 AMP? Are you joking? Have you even looked at a circuit breaker panel before?
50 AMP service is exactly how a house is wired. Two 50 AMP 120v breakers. You can either combine the legs for 50 AMP 240v or use the two 50 AMP 120V legs individually for a total of 100 AMPS 120V. The latter is how RV's are used as they don't put 240v appliances in them.
In my 30 Classic, I can and have used both Air Conditioners, computer, microwave, electric water heater and electric toaster oven all at the same time. Max power draw out of my trailer has been 40 AMPS on one 120V leg and 35 AMPS on the other leg for a total of 75 AMPS 120V. My RV power monitor tells me exactly how many AMPS I'm drawing.
When my friend comes over to camp he charges his Tesla at 50 AMP 240v at the campsite, works out well.
