Working on a rack/Rotopax setup!

Had the material laying around since right after I got the bike last year. Finally found some time to cut some prototypes! I am pretty happy with it so far! Cant wait for the temps to warm up and give it a go. My first design was really small as I hardly carry anything I can stuff in a backpack but I wanted the option to throw on some gas when I dont want to have to worry about it. I ended up extending the rear to support the rotopax. I wanted to be able to remove the rotopax mount quickly form the topside as well. Second reply shows the rotopax on the back of the bike, 1 gal and 1.75 gal.
