Amp question

Been on vacation for 10 days now. 4 total campgrounds. At first three, Fort DeSoto State Park in Clearwater, Fort Wilderness at Disney, then one in GA while hooked to shore power had no problems running both A/C units. At the one I am in now i tried running two as always power lost to rig. No circuit breakers on my rig tripped. Power back on. Called front desk and was told I could not run 2 A/C units on 30 amps and it was my rig. Turned off one. Tripped three more times with one ac and tvs going, a laptop and two ipads charging. Called and they tested the power to the pole and I dont remember the numbers, but he said they were right. End up complaing that with all running and one ac I was only pulling 17 amps at the time of the last power loss. They moved me and so far no problem, but now I am doubting if I should be running all that?

Le i said I havent had a problem for about 10 days now. Any suggestions? Or tips?
