Saturday - Day 2:
Loren came by and we got the new desktop installed.
We figured out why the deskside window still leaks and the opposite side doesn't. Drilled new drain hole. Not enough.
I spent about 90 minutes constructing and fitting a vertical squee-gee / dam for the water. It probably would've worked, but it also blocked the window from opening.

No go.
Constructed and painted a new foot for the tongue jack (it's quite nice, you're going to love it).
Figured out I'm terrible at trailer wiring (but did learn that mounting a marker light serves to ground it, and testing without mounting is an instant fail).
Went to store and got needed running lights (3) and connectors.
Sunday - Day 3:
Fixed all the lights (now that I know how).
Put the wall back together (had to remove the panel to get to the lights).
Installed the new foot for the tongue jack, greased said jack.
Rewrapped the exposed tongue wiring.
Installed gutter over the leaky window. Redirecting some of the flow off the roof might help some.
Bug sprayed.
Adjusted hinges on back door.
Started to fiddle with the side door, only to find the bottom to be water-rotted into chips. Sigh.
More to come...
