So, why didn't I finished cutting the PS bedside down?
The easy answer is because cutting and putting stuff back together isn't 100% perfect. There is a slot at the front that the front panel lines up into and of course the back has a VERY snug fit over the rear cross sill, so I didn't want a crooked bed, so I figured I would leave the back PS bedside uncut for now, cut down the blue bed floor, get the front tacked down good, cut the back loose, line up the DS bedside to exactly where I want it, get the floor square, then tack it all down. Then, when I mock up the PS, I'll line the front of the bed up, and whatever makes the back end line up perfect is where I'll line it back up at.
What absolutely floored me is when I locked the backside of the bed down where I wanted it and measured it... I was dead on my 70" mark I had made...
