what did you build the frame for the canvas top out of. got any pics?
I dont have any pics off hand but can snap some of what ever you want, let me know.
I built it (actually Tim came down and helped so "we" built it) out of 1/2" 095 wall HREW tube. I used a condiut bender to bend it. I made 3 hoops front, middle, and back. I welded them to 6" piece's of angle iron for the mount to the bed with self tappers. I did 3 "spreaders" between the loops one center and one on both left and right sides. The tarp is just a canvas tarp from OSH, cut to fit. My wife sewed it up for me. I put a piece of 1x2" wood runners in the "pockets" to keep a equal loadon the tarp front to back. My latching system needs improvement so that will be addressed when I redo the tarp. I have had it for 3 years now (I think) and the tarp is leaking water now. I plan to get through the rest of this winter and possibly next before replacing it. I built it to keep the rain on the way to the trail off my gear, but mainly the snow once I am on the trail. It sucks to have your ice chest frozen shut in the morning from the snow.
