Simple solution. If your canopies have velcro along the edges for walls, Eurmax makes a "rain gutter" that goes between 2 canopies to keep rain from sneaking between the canopies.
I've got them. The easier solution is still a 10X20. When I'm not in the shop, I make my living under canopies during the season. There isn't much I haven't tried to make my life easier.
Even a good quality 10 x 10 from ezup will require at least 2 people. A 10 by 20 will require at least 3. really, figure out what you need and then. . . Buy the next larger. in a stupid color.
I can produce a video, not that kind, of her putting up a 10x10. Dave, do you think you could do the same?
Only thing I’ll offer is, make sure the peak is vented, as that really cuts down their tendency to fly away. “First Up” is the brand I have.
