I put the roof on first, waited 24 hours before I "unclamped" the roof and put on the sides
You can't have enough clamps. I didn't.
Flat insert molding along the bottom of the side panels.
Got the hatch installed next. It fit!
Installed the exterior light. I don't have my battery yet so I hooked up the 12v to my Jeep via a jumper cable to test the lights. Both interior and exterior lights worked!

120v power inlet on the street side.
I found that the tan trim insert matched the ivory of the roof perfectly. Really dressed up the trim.
Front of tear with aluminum and trim complete.
Back of tear.
2" aluminum angle on the rear edge of the galley floor. I like the look of the stainless steel screws.
Have to trim the exterior edge of the galley and finish the interior of the hatch. The counter will get a piece of Formica laminate, I think I'm going to go with a quilted aluminum backsplash.
The 12v wiring travels from the tongue box underneath the trailer, entering between the galley and living space. I used watertight conduit to protect the wires and for a neater look.
I'm going to build the door next, have to get the opening trimmed first so I know what the rough opening is. I can taste the end of this project. The light at the end of the tunnel is NOT an oncoming train!
