Install a desk

[HaveRV.Willtravel64]

Hi there,
Have a 2021 3761FL with 2 couches.
Want to remove one so I can install a sit/stand desk for the computer,etc.
I know there's a gap where the couch sits -like a platform - in the slide.
Just want to make sure I won't hit any major wiring if I do install the desk as I would want it to have some sort of screws, mounting attachment so the desk doesn't tumble traveling down the road.
Any ideas, suggestions would be appreciated.
