I decided to varnish everything before assembly. There are a lot of places that would be difficult to reach if I waited to varnish after assembly.
Progress over the weekend included:
1) Finished pre-plumbing the air conditioner drain line
Down through storage compartment into the cooler compartment. (You can see the drain routed into battery compartment on right.)
Passes through cooler compartment into battery compartment. (The cooler fits below the drain line.)
2) Laminated panels to cover the underfloor storage compartment
3) Disassembled the dry fit
4) Drilled remaining pocket holes on wall panels
5) Attached remaining assembly cleats to wall panels
6) Sanded 4' x 10' wall panels and applied two of three coats of varnish
7) Sealed storage module with CPES and filled screw holes with epoxy putty
8 ) Cut and labeled spacer sticks to ensure all panels are located accurately during assembly
This photo shows the spacer sticks and supports that will align/hold everything temporarily in position until cleats are screwed in and pocket holes are drilled.
The plan this week is to sand all the remaining panels and apply three coats of varnish to them. I'd like to assemble the camper this coming weekend...
