The plywood floor has been sealed with 3 coats of spar varnish and mounted to the frame with elevator bolts, these hold much better than the carriage bolts and don't spin when you tighten them. I've also started on framing the walls using 4 in x 1 in ( actually 3/4 in) pine. The framing for the door frame is Oak and Popular to add strength for mounting the door hinges and hardware. Next will be to buy some 4 x 10 ft 1/4 inch ACX plywood to attach to the outside of the frame, then insulate with 3/4 foam and then put the inner wall on, which will also be 1/4 ply, not sure what type of wood but more than likely it will be either Birch or Oak.

As you can see in the pictures I received the correct brackets for the shock kit and they have been mounted. I was not real happy about drilling a 1/2 inch hole through my frame for the mounting bolt, hopefully this will not cause my frame to weaken. Others have done the same with no ill affect that I know of. "Time will Tell". It took me about 3 hours from start to finish, excluding the trip I had to make to Lowes to pick up another  1/2 inch drill bit.

I ordered the wrong mounting brackets for the Monroe retro shock kit, I ordered part RB512 and should of ordered RB511, the replacement should be here this week. I also will be using elevator bolts instead of carriage bolts to attach the floor to the frame, the carriage bolts have a small head which kept spinning as I tried to tighten it down, had to use a clamp to stop the bolt from spinning, the elevator bolts are flatter and have a bigger head, hopefully these will work better and not spin when I tighten them down. I'm starting to layout the galley area with my fridge on the right and batteries / fuse panel on the left. In between will be some drawers and a counter top across the width, above the counter top will probably be a couple of cabinets or cubbys to hold other stuff. The top off the floor has been coated with a couple coats of spar varnish and sanded, I'll add a couple more coats before the floor is complete.
