My design, the "Dragonfly" please critique!

Alright, flame away. Please criticise, insult, demean as you see fit. Now is the time to give me bad news (before I start building) and I'm actually looking for it.
Okay, here goes:
Side cutaway:
This shows the rough interior dimensions.
Wall and interior:
Galley:
Not much detail here, but I intend to have a portable Coleman propan stove. The cubby in the lower left will house the propane tank. May need to be resized to allow for plumbing. Not shown are drawers and faces.
The blue stuff is plexiglass that will serve to partition off a storage area for dry food.
Wall construction:
I'll be using 1x4s with 3/4' foam board as insulation. Too much?
So that's it in a nutshell. If you have Sketchup you can download the drawing here:

Construction:
Walls and interior ceiling/roof- 1/4" plywood, 1x4" framing with 3'4 foam insulation
Galley cabinetry - 1/2" plywood, 1/4" Plexiglass
Floor - 1/2" plywood with 2x4 framing and joists
Trailer - unknown at this point. still looking for inspiration or a good deal.
My goal is to keep the weight under 1000lbs, tongue weight under 150 lbs.
