THIS !
So glad I added two access panels on my RV-7. Even on a tip up, it saves SO MANY panel dives. Plus, it's a good 'skin patch' practice for A&P training later on.

With most of the large format EFIS displays, you have a built in quick access that is faster to get open than 24 screw heads. Perhaps even a larger opening also.

Suggest rereading posts and reasons by those who have done it.

This is what I did for access: built a pallet that sits under the skin between teh FW and subpanel, and plopped most of the boxes on that. It's attached using piano hinges to the fore/aft ribs, and drops down easily for maintenance or removal

Still have the jig and could duplicate on any 7 or 9 slider front deck skin.
