Had a 5th without generator ready. Had a dealer use the receiver hitch, and carrier on the rear. He installed all interior parts. Then ran a 50 amp. cable. It worked just like a generator that had been factory installed unit. They mounted a Kipor generator on the carrier. It would run both A/Cs easily. Bought a Cameo with generator ready and dealer had tore down a MH with a 7000 Onan. It hadn't been used much so installed it in the front compartment, and insulated it to the point you can't hear it while in the inside in of the trailer even while standing right over the generator. Thats the best way to go, but can be done without generator ready.
