I've been thinking about this a bit. I'm sure everyone would have their own little needs/wants in it. So... Here's my ideas. Take, leave or laugh at them at your discretion.
Needs to sit far enough back to clear a Milford barrier, but not by much... could even sit against it with a rattle pad in between.
Front (towards seats) end needs to be real tall - like back of seats tall - with tie down points on a rail at the top of it. I'm thinking 1/2" opening 8ga expanded steel or aluminum mesh (like catwalk material without the cleats) for the front & sides with a 1/2" square tube top rail welded to the mesh. Makes the entire top of the rail a tie down point by clipping a carabiner over the top rail through the mesh.
Sides need to be as tall as the top rail on the wheel well mounted carriers and have tie downs on a rail on top of them or use something like the mesh idea above.
Tailgate end of it is the trick... lower is better for access, none makes loading coolers easy... high keeps gear in place when the truck's tailgate is open. What about making a tailgate on the drawer to match the mesh walls idea above?
Automatic slide lock to keep it in place even if the truck's nose is pointed up when the slide is pushed in.
No rattles - it will need some way to lock it down so it doesn't shimmy-shake-rattle.
Just ideas. They may not even be good ones.
YMMV
custom built rack. Mods on 80s never ends
