I finally settled on a 5x8 layout built on a Harbor Freight trailer (mainly because I already have one).
I will try my best to keep up with this build journal but actually building will always take priority as I already anticipate a lenghtly build due to my work schedule and family responsibilities.
Want to say thanks in advance to all the great members here whose thousands of ideas I already have and plan on stealing. Too many to point out individually at this time but for the major design cues, youll know who you are based on pics hopefully.
Anyway, on to what really matters . . .Pics.
My first Home Depot run. Thats 2 sheets 3/4 sanded ply, 2 3/4" OSB, 12 premium grade 2x4's and the bag has a couple bottles of Titebond II and a nice new carbide blade for my circular saw. Oh and not pictured is a gallon of Asphalt emulsion goop.
That is my HF trailer. I bought and built this summer 2009 and used mainly for hauling my scooter and then motorcycle. Just a simple 3/4 plywood deck on there. i have since purchased an old beater truck as a second vehicle and found I rarley used/needed the trailer anymore, hence the reason I am ok giving up for the tear.
And finally last nights progress. Got the trailer stripped down and ready to build up the floor. Took much longer than I had hoped. I used way too much Locktite

Hopefully attack the floor tonight
