I still have to decide what I want to use as trim over the areas where the panels meet. I'll either cut some strips, or purchase some screen door trim if I can find some in the next few days.
After I finished wall frames, I installed the wheel wells and covered them with insulation.
The wall sides are almost ready to put onto the sides of the floor frame, just need to drill a few holes for the bolts to go through. Hopefully tomorrow or Wednesday I can get that done. Paneling the cabinetry is the next thing I plan on doing, then installing it all into the trailer.
More next time.
