If you have a large Front-Off-Rear switch in a cabinet somewhere, then your genset likely will run both ACs at the same time. But your 30 Amp shore power cable is the issue. If you want to, you can change that cord over to a 50 Amp...but that costs far too much. There are some things you can do...
1) Wire a heavy duty cord directly into the rear AC with a 120 Volt double pole, double throw relay ($10 for the relay) so when you plug the cord into a spare 20 Amp outlet on the power tower, the relay closes and supplies voltage to the rear AC. When it's not closed, the Genset does. The cord is just run through the bedroom window. Since most power towers in RV parks are near the rear of the drivers side, it's not that difficult to toss it out and plug in.
2) In the genset compartment, there's a 4-square metal box. You remove the cover, find which wire goes back to the rear AC, then install a switch between the genset supply, and a heavy duty extension cord which plugs into a shore power 20 Amp outlet. This is probably what you're thinking of about the article you read.
Of course you could get all fancy with a 50 Amp adapter adapted just for this purpose but simple is better. And cheaper.
