Remove 50amp genset and replace with 50 shore power

I would not remove the genset.. instead upgrade the RV to 50 amps (new cord inlet and transfer switch new breaker box.

Alternate is the PSRV solution.. Find the wires from the generator TO the 2nd/ AX Split them off to a second 20 amp plug.. Run a new 20 amp lead from where the A/C was connectd to a 20 amp (OUTLET. use a 12ga cord to the park;s 20 amp outlet and you have both A/C.

NOTE: 30 amp is 3600 watts
What you suggest gets you 6,000 watts

Upgrading to 50 amp. FULLY upgrading you get 12,000 watts. and better power feed as well (long story highly techical as to why it is better)

The only draw back I see with removing a working generator is when you are traveling down the highway in 90+ degree heat you will have no power to run the A/C.

Thanks. According to specs, that's not the same thing as 50a service. 50a is two hots each of 50a for a total of 100a.

That's just a big regular generator. I think Mr Wizard said the same thing.

The Marquis 7000 has two windings, one feeding a 30 amp breaker, and the other feeding a 20 amp breaker. I expect that leads to the "50 amp" confusion. Onan's Emerald Plus 5500 even has a large "50 amp" sticker on the front. :)

Going to sell generator since its never used and needs some work. Why carry that extra weight and take up the space, Maybe put a small air compressor in its place.

^^^ This ^^^, what Dutch said. It will be simple, inexpensive, and you will have the best of both worlds; you'll have both A/C's when on shore power, and still have the generator, which powers everything already. The only new procedure will be you will have 2 cords to plug in to the pedestal; the existing 30A shorepowr cord, and the newly added 20A service which you'll simply plug in to oneof the 20A/120V receptacles in the power pedestal.

Yup, a viable "work around" to true 50 amp wiring.

BTW, very unusual to have a 7KW generator with 30 amp wiring.

looks like several options. Thanks All

There's a simpler way to get power to both A/C's that works even on most 30 amp sites. It involves determining which hot and neutral in the generator wiring junction box feeds the second A/C. That pair is brought out to a 20 amp plug and socket that can be unplugged to connect a 12 ga extension cord that plugs into the 20 amp utility outlet found on most campsite panels.
