Thanks guys for the kind words!
Moving around in the shop this week with fresh painted parts has been stressful, trying to be sure & not scratch anything. Had a few things to finish on the bed before it got set back onto the frame.
A LWB bed's inside wood length is actually a little more than 8 ft long
So decided to leave the gap at front & used a piece of 1" tubing to fill that space. For the bottom, made a few plates to help support the center where sheets come together and keep them pulled down evenly. We'll silicone the cracks, from top, then once it is all sprayed with bed liner should pretty much look like a one piece floor. Still glad I went with the marine plywood floor, since only have about $400 in it verses the $1k+ in a wood kit like original. Don't get me wrong original type wood beds are beautiful, but I want to be able to throw stuff in this & not worry about it.
We gathered some friends with good backs & muscles and now it looks like a truck again!
