Welcome to the Campfire!
The camper looks good! I like the door - so many camper/TT doors are too small for me. I had to squeeze sideways into a buddy's 13' Scamp egg TT.
I have been gathering ideas for a utility trailer conversion, and will use a similar lift-up roof idea to proved clearence to load/unload a motorcycle in it.
The "Teardrop&TinyTrailer" forum gives me lots of ideas, like for light-weight construction. Some guys there are using a 1/8" plywood/foam sandwich panel system for the sides and roof. I want to keep weight to a minimum to tow behind my V6 minivan.
Will you have onboard water & gas, or just use camping stove and jugs?
