Yes, a deep bench becomes a crap magnet, collecting all kinds of stuff that needs to be moved when you want to load.I'm actually thinking of ripping the door in half and making a bench top out of one half and a lower shelf for storage between the legs out of the other. If I wrap the upper half with 3/4 inch white oak edging that would give a ~21"-22" deep benchtop which is plenty deep and 80+" wide. I'm a big fan of mounting the bench to the wall. My present bench is 4x12x8 cvg fir and it was stout before wall mounting, but when I fastened it to the wall I was amazed how much less deflection there was.
This is kind of stupid on my part since I already have a good bench, but I got a wild hair to make a new one.
Edit: spelling and measurements
Well. for me anyways, and the reason I went vertical and built a loading cabinet, with a bi-fold door to keep out curious little hands.
I stand to load,
