Well I'm glad I have some help to install all of this. Looks like I bought the wrong inverter which has now been 2 months from Amazon and I can't return it. Should have bought the 2x unit because this is a 50 amp coach. It does 240 volts which this will only do 120.So we are going to have to get creative with the wiring and put in a separate AC panel with three breakers in the battery Bay. Then we will be able to run the 120 side of the hot water heater. I will not be able to run the block heater on the motor which is fine. I will not be able to run the AC units which is fine. No problem running fridge, all the receptacles, and the microwave.
