We found an older model of the Kelty Carport on sale at Sportsman's Warehouse for $50 this spring. It is a slanted model that won't pitch out perfectly horizontal like the newer $300 model. But it worked very well in a cold driving rainstorm with some wind last Memorial Day. We staked it down and attached the top to the top of our awning and it worked perfectly. Absolutely no danger of it coming lose and pummeling the side of the van. I would get rid of the Fianna awning at this point, but it would need to be replaced with a horizontal bar at the same height to attach the carport.
Here's some pics of it set up:
Notice how the SMB cargo door easily clears the Carport, something it doesn't do with the Fianna awning.
