Plywood construction is the biggest shortcut I can think of. Any time you change from plywood to frame built, like I am doing, you increase your build time by a factor of 10... hmmm. maybe by a factor of 20. You get the idea.
If you have your trailer ready to go, build the body one weekend, and paint it the next.
You can always putz around in it after that, adding a light here, a battery there, or whatever.
Keep up the research, it'll help a lot.
BTW, you have a digital camera, right? We here are all counting on you to take lots of pictures the weekend you build!!!!

P.S. You've seen our progress, right? It's going so slow because of the framing...
