You don’t say where this is located weather wise. If the weather is not too hot, you can get by on 30 amps. Once trailer is cooled down, the 15k rear A/C on ours will keep the trailer cool if temps are 95 degrees or lower, and maybe at least some shade. But then ours is only about a 35’ rig.

BUT. It can also be annoying, because you will have to manage power carefully. If runnng A/C you will probably have to run water heater on propane. A/C plus water heater plus microwave or other high current device such as clothes dryer will likely trip a 30 amp breaker. No real problem as you just reset the breaker and try not to do the same again. But still annoying.
