Just took a short up and back through a section of the Idaho BDR. Some folks at Burdgorf thought my riding companion was interesting so I thought I'd throw this out here. I call him Berne because that's what his name is. Sewed the legs closed, put a zipper across the torso, took the loops off the back and sewed them to the front so they wrap under and hook, some D rings, Scotch guard - you get the idea. Tool bags and heavy gear in the legs, stuff the sleeping bag across both, thermarest and bivvy in the top with food, water, chain lube and attach with cam-lok straps through rear seat tugger strap and piece of paracord through the rear fender. D rigns on the bottom of the legs to nylon strap wherever it attaches. Right side is back a bit so I can kick the bike. It's been working for me for a couple years.
