The RV's panel doesn't care - you could max out one leg and have nothing on the other leg without any heat, etc.

The NEC standard is for the normal connected load on a circuit breaker should be no more than 80% of the breaker rating. Two ACs, a water heater, and an outlet or two could easily exceed that.
