Got the windows installed. Very happy with them. (These are windows ordered from Lil' Bear Tagalongs - Thanks Grant)
The walls are up, glued, and screwed. This was a happy moment. Seems like it took me way longer than I had planned.
Here the front bulkhead is installed (and rear bottom galley and counter). I used the Kreg pocket jig extensively - wow it that slick!
This view is from the back of the trailer looking forward. The headliner goes in next.
I put the bulkheads in first to stablize the walls, get the spars in, and then put the headliner in.
