Subbed and curious why you're not facing the L-steel the other way but will wait for all to be revealed.
Actually thanks for asking that because it prompted me to look back into it to remember why I did it that way, and you might be on to something, I may be able to flip them.
I wanted it that way initially for more width, but at the time I thought I was going to need to use the same L-steel for the inside of the slide as the steel bolted to the floor and was going to run into bolt heads in the way and such. Later I ended up going to a thinner and smaller L-steel (huge weight savings) on the inside, and didn't go back and re-check my clearances.
I might gain about 4" of width for the cost of raising some stuff up less than 1".
I still may run into a problem with the stupid bump that is on the threshold to the cargo area. The wider you go the more in the way it becomes. I think if I do flip it I've not done anything yet that will make anything I've done not work, but I need to mock it up that way in the truck and check for clearance issues.
I guess everyone is curious, but the big difference between what I'm working on and the typical drawer setup is I'm not going to enclose it like a box drawer. I'm just going to make a big flat platform that moves. RockyMtnX did something very similar except his sliding shelf went under another platform.
Then I'm going to try and rig up a HF cargo carrier shelf kinda like what a bunch of you here have done (I think @Longboardr
is the one I referenced most) to attach on top. Really that is a separate task though, I'm going to make it part of my slide system but it would not need to be.
I still have a problem in that I don't want to eat up the space to the drivers side of the cargo area. I've found a tent cot, and/or a folding table fit perfectly there on end, and I don't want to mess that up. However it will probably be worth it to just find another home for such large items if I have to, I do after all have a huge GOBI roof rack.
I'm going to pick up some more supplies tonight, hoping to do some work over the weekend to get it where it looks like something. I know I won't get it finished but I'd at least like to get it roughly assembled.
