All of my radio equipment, 12VDC sub-panel, 12VDC wiring stubs, antenna connections, heavy cables, heavy frame grounds, are all under the rear seat of extended cab F150 Truck. Only the control heads and floor mounted speakers are up front near my console area for easy viewing. I had one spot where the vertical part of the console met the horizontal console and was able to mount three control heads in this area angled up at me. I actually used the three gang nice black shinny finish switch cover from LOWES that has the large opening for the specialty switches etc. I VELCRO'd my control heads to the this plate. Very professional looking install.with no wires visible. I think the only part I covered up on my vertical console was a tissue holder hole or some small catch-all area.
I would do something similar if I was dealing with the doghouse in the motorhome situations. No need whatsoever for some big hunk of radios need to be up front. Only the control heads and speakers. I have the ICOM 706, a couple of 2m/440 different brand transceivers used mostly as scanners, and two 2m/440 comet antenna on the back side of the second door on my truck near the back of the cab and my Tarheel LIL TARHEEL screwdriver antenna on the driver side of the truck bed up close to the cab area. All works out pretty good but I never could get rid of all my motor interference on the ICOM 706 install. Its liveable but could be alot better.
On my OFF-ROAD POPUP I have about all the same setup except I move the ICOM 706 back and forth from the truck as well as the TARHEEL antenna.
I know this isn't for your motorhome but maybe showing what I did to populate my OFF-ROAD POPUP setup will spark some ideas. I love to use BLUE SEA products every where I can for 12VDC distribution. This layout shows where all my radio and antennas are installed around my POPUP. The area where my control heads are installed is my wrap around seating inside my POPUP.
Good luck with your console setup...
