TV, AC, electric fireplace are all A/C 120v. No influence on hydraulic 12v pump.
The wiring is over kill so no problem with overloading wiring to pump. If Lippert recommends (see Lippert bulletin above) then no warrantee issues either.
What you need to remember is the pump load is the same regardless of which breaker is in the line. The only difference is when you have a slightly higher draw it won't trip the 80 amp breaker. If there is a catastrophic failure (short or blown pump motor etc) the breaker will still trip.
In the OPs case it sounds like the breaker was worn out from tripping a lot. My guess is after awhile while on a trip or after storage and battery(s) are a little low on voltage the pump amp draw will go up and it will start tripping again. If not, great!
