Pathway X2 and 2017 GH 29 MV wiring

[Baldfacemt]

Hi ,
Just bought hubby the Pathway 2 and Wally receiver with Dish service for fathers day. I've gotten it up and running however we wonder if there is a better way.

I think because the power to the satellite is provided by the coax from the receiver that there is no way to plug into existing cable in or sat hookups in the compartment provided from the factory, right?

So that means the coax is currently running out the door, anyone have a better idea? Trip hazard for sure.
We are considering drilling down through the floor and then into the compartment by the steps then keeping to coax in there so as not to have to hook everything up every time we stop....thoughts?

In addition, the Wally receiver doesn't fit in the compartment over the door as we had hoped so Hubby wants to build a shelf attached to the cabover bunk right under the TV so he won't have to drill through the wall for support.

We would appreciate if anyone has done any mod to send pics or if there is a better way we are missing let us know before hubby starts drilling holes!
Thanks,
Gayle
