I built a duplicate of your cartop carrier (4" thin walled PVC, 80" top segments ziplocked to my Jetta Sportwagon roof rack). However, I now realize you are a bigger stronger lad than me, as I struggled to get the bow positioned on the yoke for the final push upward (I'm a 5'10", 190 lb, 64 year old, reluctant to begin a weight lifting regime). A larger friend stopped by and helped me out this one time, so everything else is fine. Perhaps with practice, I could do it. Do you have any tips on how you positioned the bow upon the yoke solo (not shown in your video)? A longer yoke that extends all the way back to the ground (a smaller incline) would no doubt help, but then I would have a much longer carrier to carry.
