Are you sure you are showing watts? I have issues with triping the pole breaker. You have to be carefull of all you may have on. If all the ac's are running and the electric aqua hot is on you will over amp. You can not draw 50 Amps or 6000 watts on single leg for a long period of time before the pole breaker trips. What is running in your coach when this is happening?

Unplug remove the cover from transfer switch you will see 2 blue plungers. One is shore power the other is generator.. Turn generator on note which plunger engages.. Turn generator off. Plug coach in push other plunger down with something. Preferably non conducting. See if plunger stays . If plunger does not stay down. Wedge it with something examine amp draw.. May let you know if the plunger is fully engaging..
