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)
