15. Made spacers from tube for the mounting bolts so that they don't crush the qubelock when tightened (thanks to my future father in-law for the hint) and used some SS bolts I had lying around.

I am not happy with the turnbuckle fastening system. They will only just turn when attached, and regardless of spreading the load I feel like they could/would tear through the qubelok. Then again if they get loaded like that, the vehicle will probably be upside down and some damage to the drawer frame will be the least of my worries. Thinking a pair of diagonal ratchet straps over the whole assembly might be a better go. Or a skirt of saddle clips and rope webbing. Unsure. I feel like I am making it more complicated than it needs to be.
Any good suggestions?
