We are in Florida so run the A/C a lot and had a similar issue. What I figured out is that the 20A and the 30A breakers are combined (which is common in a ton of travel trailers) into one single pole breaker. With the A/C constantly on the 20A side would get hot and since it was combined with the main 30A which is handling the total TT load it would trip. With the heat and frequent tripping the breakers wear out and can't handle the load.
To fix it I replaced the combined 20/30 with a single pole 30A for the main and added a single pole 20A for the A/C to one of the expansion slots on my board. The upgrade/fix cost me less then $30!
