Forward tanks and sub-floor framing

Installed the forward tanks (1 grey water, and 2 fresh water) and began work on the forward floor framing. As in the aft cabin, the tanks are 3/8' wall, roto-molded polyethylene from Plastic-Mart in Southern California. They sit in a "tray" built up out of 3/4" ply with a 2x3 frame that will lock the tank in place. The SS threaded rod at each corner of the frame is for hold downs.
