Generator to run three RV's?

I've never overloaded my yahama 3000sieb, except when deliberately trying to do so. To be fair, I do have a load support inverter/charger. The generator does have remote electric start and I use it sparingly.

I do use a watt meter--and on shore power I've never used more than 7200 watts peak load (how--I have 2 auxiliary shore power cords). Average load at -30 is about 4300 watts (per hour so 4.3 kwh). But we are talking summer time, and the living is easy.

My rv behaves as if it were on shore power full time.

I deliberately limit my 30 amp consumption to 23 amps, which is what the Yamaha outputs.

23 x 120 = 2760 watts peak load when boondocking.

In the OPs case..

2 RVs with 50A shore power = 24Kw
1 RV with 30A shore power 3.6Kw

Fair chance that the folks with 50A shore power will easily end up tripping the gen. Their rigs have a 50A breaker so they can draw 50A (6,000W) on each leg which means the generator breaker now becomes the limiting factor.

Not everyone understands the idea of "conservation", energy management or energy sharing.

Very few RVs are factory built with battery "load support" which uses a big inverter and battery bank.

A lot of rigs with 50A shore connection are large enough to have two 13.5K BTU A/C units or at least one 15K BTU A/C unit.

One big 6Kw or larger gen most likely will require some shed to allow the gen to stay, lifting and moving 6kw+ gens isn't easy, perhaps if one was a body builder then the weight of that size gen would be a simple warm up exercise.

Your attempting to split 6Kw across three rigs, essentially is the same as attempting to run a 13.5K A/C from a 2Kw gen.. Some folks have been successful under ideal conditions with a bunch of mods, but more often than not, have failed at that attempt when conditions like temps and elevation are less than optimal.

A 6Kw gen would be easily swamped by just having the A/C compressors on three RVs attempting to start at the same time, it isn't like you are going to sit there and load manage by attempting to time the compressor start up each time each rig needs to turn on the compressor.

I can assure you, once you step above the small 4Kw gens, the noise level and fuel consumption get much worse.

Far better to have each RVr bring their own 3.5K inverter gen to the party, it will be less noise, less fuel consumption and each person must handle their own gen issues like fuel and noise..
