I'm curious, are the pictures not showing up on your screen? I'm wondering why the repost of the lower cabinet pic? There should be 14 pics in this post; at least they're there when I look at it

The "gumdrop" design is just a case of form following function; more space, but the hatch is a lot harder to make. I had to make some ( a lot, actually) special tools to build the hatch and bend the front curves.
There's a twin 12vdc light in the hatch (high and low) and a battery operated 3 stage LED light also. Inside, there's a white 12vdc LED light and another with red LEDs. Also another battery LED backup light.
The lower galley cabinet has a holder for twin gas bottles and a fire extinguisher, otherwise it's a "big" space for larger objects.
Don't know about brakes on a trailer this small, you could try here:

They're right around the corner from me; good people.
Thanks again for your comments.
