Thanks, everyone, for all the kind words!

It's been a lot of work but a lot of fun building the trailer. We lifted the body off the frame in order to beef up the frame to handle the extra weight, and also installed a new heavy duty torsion axle and a new floor. The oven is a Forno Bravo casa 90, 36" floor.
Back in the 60s, shiny aluminum Christmas trees were popular. The color wheel has a built-in spotlight that would project colored light onto the tree. It works well against the white walls in the trailer. Kind of psychedelic looking.
We've had the trailer out a few times so far with fairly positive response. I honestly don't know if this will ever be anything more than a hobby business. We plan to spend the winter planning for next year and possibly expanding our menu beyond just pizza a little bit. We're fairly space limited, so we can't get too carried away.
