Here is a short summary of my journey! Followed
@unfast and attached the wings with magnets. Used wood filler to even out the extra holes on top. Also added flush hatch pulls to the wings to help with removal. For the drawer pulls, I had purchased BOTH large basic handles and vector T handles. Painted everything with rustoleum flat black (temporary, for now). Covered the drawer bottoms with rubber tool box liner.
My first attempt I guess I was being a little lazy and went with large handles mounted on the bottom inline with the slides and was going to skip the vector handles altogether. I guess I figured this would give a more solid place to pull in case the drawers were sticky (for the record, they weren't sticky).
So it was back to the drawing board. It turns out that the clearance right there is very tight, especially at the bottom with the gate closed. At this point, feeling stupid, I figured I would just go ahead and install the vector T handles I already had laying around.
Mucho better!! In hindsight, I am so very glad that I went the extra mile to install the vector T handles. The action is smooth, the pull feel is great, and now I can lock my drawers! At some point I will change out all of the exposed hardware for security bolts so I can use it as semi-secure storage. I will also need to find a better way to secure the magnetic wings... while I like being able to quickly remove them I notice they can flip over if my dogs step too close to the edge. Problem solved for now by stuffing crap underneath and pushing the dog beds to the corners. I was also planning to cut off the sides of the drawer face and bolt them to the frame, but I've decided to leave them as is. For my intended function (dog platform) I decided it is useful to be able to access to the side compartments from the front. I haven't installed the bottom trim thingy yet but I will eventually when I'm done fiddling around with it.
Also, to those who are interested, I discovered it is possible to drop the gate, close the upper hatch, and the drawers will still function 100%. Works great for keeping the dogs in the back while still being able to use the tailgate and have full access to the drawers.
I want to give a big thank you to Dave. The directions that are included are some of the best I have ever seen for any product (bar none). I can tell that the system has been engineered to very precise tolerances, but it was a breeze to assemble and functions exactly as I imagined. This kit is awesome and is a perfect starting point for any custom drawer system!!
