Anyone out there upgrade and install an inverter in their Momentum. I called GD and they offer a 1000w option in the WF-5110-RS. I just need to run a few things at night (Cpapx2) when my onan gen is off. I'd liek to get my hands on a wiring diagram or at least a diagram to map off of. The 1000w they install has its own transfer switch. Im guessing it goes between the line from gen to the converter. Not going to pull the trigger until i know for sure how and where this is installed.
