Yes, BUT, what he did is way more than is needed. The best way is to use the standard 30 amp power cord. Then install a 30 amp Auto transfer 120 volt box where he added the 2 extra outlets. The Genset feed goes from his original 4x4 box to the genset leads on the Transfer box. The OUTput to the rear AC goes to the output on the transfer box and the 30 amp shore cord is connected to the Shore cord INPUT on the transfer box. In this set up, it is ALL automatic, you do nothing but plug in the extra shore cord to run the rear AC and do NOTHING if you want the Genset to run the rear AC. Doug
