Jayco just installs an INVERTER ONLY for the Residential refer installs. That Inverter has PASS THRU power. That means when you are connected to Shore or gen Power, the 120 volts goes thru the Inverter and the Inverter if ON, goes to stand by. When the 120 input is disconnected the Inverter then starts Inverting 120 power to the refer. There is nothing you have to do other than install the Genset and connect the wiring to the Genset. IF the Jayco is prewired for a Genset, the 120 wiring and the Transfer box should already be installed. I have NEVER seen the Leveling system control box on a Jayco installed in the Genset compartment. This must be something new Jayco is doing. They usually install the Control module in the first Storage compartment ceiling in the middle between the sides of the RV. I know people complained of that because when they needed to access the fuses and such, they had to remove all their storage items they stored in that large compartment. Doug
