50 AMP and plugging in at home

[Timothy2001]

Although new to this, I strongly suspect that a coach that has 50 AMP service may not be able to run A/C in the Texas heat on an standard outdoor extension cord plugged into an exterior house outlet. I'll make the assumption the generator can handle but would prefer to run off the electricity from the house when here.

Do I need to install a new breaker at home that has the capacity to power the coach including the A/C units on a 39' coach?

Tough one to answer without knowing the specific coach that you have. My coach has a 50 AMP service cord and I have run ONE AC unit when plugged in to a standard 20 AMP service outlet before at limited locations.
When I do that I have to put the WH on gas and carefully manage my other power usage. I have to turn the AC off if I want to use the microwave but I am able to have the TV turned on while running one AC unit on 20 amp service. I do turn off the battery charging portion of my inverter, which can draw a lot of power.

Yes, you do need 50 amp power to run air/con.
