Finally figured out sketchup enough to work on an offroad trailer design w/ inside seating. This is for quick 2-4 day trips into the more remote areas of Utah.
Tires are 35" x 12.5" - same as my jeep.
bed is 60" x 80", and built over the top of the wheel wells.
body is 5' x 8'
the foot of the bed can be lifted up for access to a foot well, allowing comfortable seating. Add a drop down table and some kind of seatback, and it should be a comfortable place to avoid poor/cold weather.
these initial sketches are mostly about validating that the footwell doesn't hang down too low, and if the overall height is reasonable (80")
