All my outlets inside and out are on the same breaker. If the coffee pot is on and the DW turns on the hair dryer, the internal breaker will trip. During the winter, I use a mid size room ceramic heater as we camp year round. The heater is fine, but turn on that coffee pot or hair dryer while the heater is runng and click, the breaker is off. I do have a solution! I have room for a couple more breakers in my power center, so a mod this summer will be to install a breaker and an outlet in the middle of the TT (near the entertainment area or under the fridge) just for the heater. Considering the current draw of the AC, which you aren't using when the heat is on, my calculations are that the heater can be on and the coffee pot OR the DW's hair dryer can be on at the same time.
