We have been told we can but not advised. With almost everything else off except residential fridge it is still too close to limits of available juice. Wondering if others do actually run 3 units and how it has worked out. Thanks

We did use all three coolers for most of yesterday afternoon and it cooled nicely. Thanks everyone for the info.

No problem if proper 50 amp RV service (two 50 amp hots) AND properly wired coach (one each A/C on each hot leg).

One of the units needs to be on the other leg. There are 6000 watts available on each leg. In theory four units could be run, two on each leg.

True 50 amp service is actually 100 amps total. Three AC units should be able to run, along with other appliances IF all three AC units are NOT wired to one leg of the 50 amp input. If all three are wired to one leg on the incoming service, than 50 amp is the limit on the AC units, but that should not affect the other appliances on the other 50 amp leg of service.
Of course if all of the AC units are wired on one leg and that leg trips on the park pedestal, it will shut off both legs since the breaker is tied together.
