50 amp in a 30
If I plug into 30 amp service at the RV Park, what can I run. Obviously, I wouldn't attempt to run both a/c's, but if I can get by with one, the park would be convenient for us. Thanks.

I use load support from my inverter charger.
What is this?
MOST INVERTERS DO NOT but a few higher end inverters, can see the hertz from the pedestal and match it's output. This allows the electrical system to draw from both the pedestal and inverter simultaneously.
Particularly useful for short term peak loading. Let's say, you are drawing 2700w and want to run the 1000w microwave for 5min. With just shore power, that would put you beyond what a 30amp outlet could theoretically provide. In this case, the inverter could throw a few hundred watts at the problem for 5 min to support the loads. Then once done, it could pump the power back to recharge the battery bank.
This won't work well for high long duration loads. Let's say you are running 3000w for 2 air/con units plus an extra 800w for fridge, TV, lights, etc...on a hot day where the air/con units are running continuously. That would put you at 3800w. Load support might be pulling 800-1000w off the battery bank...unless it's a really big battery bank, it will go dead very quickly.
