I believe you may need two more Dillon’s. 😀I too have a OCD for benches and reloading stuff in a spare bedroom. So after 40+ years of reloading there are 5 Dillons mounted on 24"X60" benches with plenty of drawers for storage. It does seem that it is an ever growing system.
One bench is located at a right angle to the wall and in the center of the room. The front side is clear for access to the drawers. The back side is where the presses are located. Works for me!
You have a great deal of superfluous equipment cluttering up your space; can’t you find another place to park your car? You have a nice setup.It is not tied into the wall. But at +/- 500 LB. it is pretty stable. The top is 5/4" white Oak on top of two layers of 7/16" plywood. Six legs instead of four.
More recently I made a freestanding bench with drawers on both sides for gun maintenance, scope mounting etc. Some Brazilian cherry flooring left over from a house addition made for a nice top.
