If you have two air conditioners in your setup perhaps you can wire one unit to a separate 20AMP cable and plug it into the 20AMP Service on the camp ground pedestal.
I do this all the time with portable oil filled electric heaters... On a couple of long stay outings I have brought along a 8000BTU Window unit from the house and plugged that into the camp ground pedestal... Just sit it in a RV window after we setup.
We always use GOOGLE MAPS on the road and search for RV PARKS along the way. Usually find alot of camp grounds this way - click on the site for more info...
just a thought...
