Soo far i really like the lock n roll. I have the newer version suppose to be stronger.
Alright started on the floor system this weekend. Picked up a pocket hole drill pretty cool.

Got the 1x4 system built

Splined the 1/2" ply to make it 52"x108" screwed and glued the crap out of it.

Just weighing it down, have the insulation standing by and the top sheet ply for the interior floor.
