You can this rain gutter setup to connect two Caravan 10 x 10 canopies. You're not connecting the frames, mind you, you just attach this gutter quickly and simply between the two canopy tops (situated next to each other, of course) to create a completely covered area that comprises both canopies and the gutter-protected area. The polyester fabric gutter diverts rainwater in the area between the canopies, so you essentially end up with a 10 x 20 foot covered area with a handy gutter system in the middle.
Many owners find that this allows them maximum flexibility outdoors. When the weather is nice, they can arrange their canopy or canopies wherever they please. When rain sets in, though, they can connect two of their own canopies or hook up their shelter with a friend's to create a comfortable, dry environment for everyone to enjoy.
If you spend enough time outdoors, you're going to run into some inclement weather at one point or another. It doesn't have to be a disaster, though, and it doesn't necessarily need to even be that inconvenient. Being as unpredictable as it is, the weather may dictate from time to time that you use a Caravan Canopy Rain Gutter system to keep your friends or family dry and having fun when bad weather threatens.
