So based on all of the excellent suggestions from joeinternet and others I purchased the components and have temporarily wired and tested this configuration. My next step is to pull the 12V power line from the ceiling where the prewired Wingard 360 Plus that came with our RV is located and use that as the power source and finally tape up all of the connections. I'll also build a box that will mount near the Wingard port to contain, hide and secure all of these components similar to the Basecamp housing for Peplink / Wingard 360 Plus configurations. Basecamp 2.0
The Wingard power source is probably shared with lights or other components so eventually I may run directly to an open circuit in the fuse box or directly to the battery. I've included links to all of the components and a photo of the temporarily wired components.
Any and all feedback / suggestions / recommendations are most welcome.

Note to GL.iNET - there may be an opportunity here to build a tool similar to the Basecamp housing for the GL X3000 and GL XE3000?
