Just don't let it ruin your fridge or AC with too little electic coming in. We had a Montana and hooked up to 30 am for a short time. Ruined our AC and fridge. Everything worked fine after both were replaced. Only used 30 amp in an emergency and really watched what was turned on at the time. Low power can do damage.
Hope you also have a surge protector too.
If you camp in the south in the summer with a 35 ft 5er and you are not in lots of shade, you will neeed 2 ACs. I live in southeast Texas and have a 32 ft 5er, I need a 15,000 btu in the living area and a 13,500 btu in the bedroom and they do very well even in the sun. The 50 amp service will be needed and keep in mind, 2 ACs running, two laptops, two TV playing and the water heater, coffee pot, hair drier etc. you will be glad that you have 50 amps. Good luck
Get one that has 2 30amp plugs. Gives you 30 amps on each leg, 60 amps total. You can run both AC's this way. 20 amp plugs are GFCI if they are up to current code, and they will trip.
Where do you plug two 30A plugs in at the pedestal?
Many of the Georgia State Parks are set up with 2 30-amp plugs and 1 20-amp GFCI outlets in the pedestal. So for us it is worth having the "cheater box".

Some CG's are set up this way and the second plug is available if the adjacent site is empty.
But with 2 30A overloading the neutral is also possible unless the 2 hots are on a split phase circuit.
GA parks aren’t set up to share the pedestal, there is one for each site. I don't know for sure that they are split phase, never checked between the hot legs. But I do know that often there will be a few volts difference between the 2 circuits. And that difference was repeated on 4 sites at one park.
