Ready or not here I come.

Hey Mike, ya got me, I'm hooked and think I'm ready to start.
I've been reading everything I can get my hands on for a couple weeks now, and think the Weekender is going to be my first project.
I just sold my 6 MPG gas guzzeling motor home and want to get back to the basics of camping, but have a couple questions before I start.
I want to go with a 5x10 weekender, so should I build a 5x9 frame?
I want a full 7 foot bed. Plus a bit more galley space.
I also have a question on the walls, if I build a frame out of 2x2's and skin it with 1/4 luaun outside and 1/4 paneling inside it that strong enough?? Or should I go with 1/2 plywood outside and 1x2 strip frame with 1/4 inch paneling inside ? it will be insulated and I plan to use the epoxy paint on the outside.
One last thing, how come I have not seen one tear drop from the "Land of 10,000 Lakes" Minnesota?? Come on Guys I know your'e out there.
Thanks, Gadget Man, Central Minnesota.
