I went with a quick build on mine. I have had it on the road for over 5 years. Ash framing, fir slats for top, ash plywood for sides. The side boxes are pine. I did drop the top down about 4 inches as it looked to tall and narrow along with the wind really blew over the top of the windshield. The next change would be to enclose the cowl area a little more.
