7500 watt generator.

I have a 2014 Forest River Crusader 360BHS. Myself and two buddies are taking trip from Thursday to Sunday in a couple months. The place we are going is pretty much a parking lot they are allowing campers to park on so there are no hook ups. We do get a portajohn with our entrance fee so that is good. My question is will a 7500 watt generator run both my ac units at the same time. I think they will but if anyone has done it I would like to hear about it. Thanks.

7500 watts / 120 volts = 62.5 amps.

Each A/C will pull less than 15 amps.

You’ll be fine.

I don't think you'll be be able to hear anything, with a generator that loud.

My Briggs and Stratton home gasoline generator in that power range is about one degree less annoying than a leaf blower. When the power goes out at home, you can barely hear it inside though if doors/windows are all closed. On pavement through the thin walls of an RV....I think I would rather sweat than listen to that thing drone on and on.

theoretically yes it will run both. with two a/c's i'm assuming you have a 50 amp trailer. and it appears you have not connected the generator to the trailer before. if there was a concern it would be how the 50 amp rv cord connects to the generator. is there proper receptacle on the generator for the 50 amp cable? or are there a pair of 30 amp receptacles on the generator? you may be fine but hook it up at home before the trip and verify that it will run both a/c's.

A 50a shore power service is 6000w on EACH leg. (12,000w total)

A 7500w generator will be marginal but should be OK to run BOTH A/Cs at the same time with some power management.

Make sure you have the proper connection to utilize the full wattage of the generator.
Not all generator outlets are created the same and provide the full wattage.

A parking lot, with a porta-potti, with buddies, Thursday through Sunday, "in a few months", sounds like a NASCAR race fan RV lot.
Racing makes a lot of noise but be polite with your RV neighbors when running what sounds like a construction site generator.

Sounds like a open frame construction generator. You will not have many friends if you plan to run more than a few hours during the day.

I think you will be fine power wise if that is what you plan on running. You wont be able to run everything at the same time (electric water heater or microwave). The two ACs should be fine with that size as long as they both don't start at the same exact time and even then you may not have a problem.

If you have a hardwired EMS you will want to test before you get there or learn how to bypass it. Most generators require an N-G plug to function and some generate an irregular sine wave that will trip the EMS.
