I fabricated a shelf and some rails!
Sadly, don't have pics of it installed ... basically this is just inside the glove box opening.
I am bogged down trying to mount my VPX and a remote radio (garmin) in the area forward of the sub panel on the right side. I want to be able to remove them if necessary. Ideas and pics would be much appreciated.
Late to this thread. I've done drop-down trays on both sides and shelf inside glovebox opening for backup battery and backup alternator regulator. Also a plate inside upper part of glovebox opening where I will mount the relay and power distribution panel for electronics/avionics. I'll mount a small fuse block on the right subpanel for a couple of items that couldn't fit the main breaker panel.

Ingenious location choices. As those of us with full panels have discovered, like fitting 10# of potatoes into a 5# sack . . .
