When we have electric hookup, I run ac, microwave, TV, water heater, and others, sometimes all at the same time on my 30amp, and rarely trip a breaker, in that rare case, it's usually an individual breaker, not a main.
You may be looking at doing something unnecessary.
If you are running the air/con, microwave, tv & water heater simultaneously and the 30amp breaker isn't tripping...something is seriously wrong and you need it to be checked out. That should be up around 35-40amps of continuous draw and should trip the breaker. You might get away with the air/con and one of those items (say air/con and microwave) but certainly not all of that. Normal solution is to switch the water heater to gas and turn off the air/con for a few minutes to run the microwave.
If you upgrade to 50amp service, even if you leave it all on 1 leg, it should be OK but really if you are doing that, I would split out the big loads onto separate legs as there would be no cost or complication in doing so and it keeps both legs at a relatively low percentage of max output.
Someone else mentioned that it is 50amp 120/240v, which is true but that means you have that coming into the panel. Leaving the panel, it's two legs of 50amp 120v. It is almost unheard of for even large rigs to have 240v appliances and obviously a 30amp 120v rig won't have any 240v appliances.
Of course, this all presumes, you are plugging into a 50amp pedestal. If you are plugging into a 30amp pedestal, a new panel won't do much of anything for you.
