Peragon is kind of a cross between the trifold and a rolling cover. No canister in the way, and you can easily remove the cover if you need the space.
The problem with the Peragon is that you can't load the bed and then close the cover. The 'accordion' pieces drop into the bed. When you try to pull it out, the pieces hit whatever you loaded into the bed and it won't unfold.
So you get to close it all the way, then crawl into the bed to load your cooler, suit cases, etc. at 5AM in WinterPark in February when it's 14-deg outside so the cover is closed when you close the tail gait and start the drive home.
I sold mine b/c of that (it was on the truck when I bought it). Got a soft roll up type and it's fine. I don't leave anything in the bed so that's not a concern. The Lomax folds up but then blocks the rear window if you need to haul something with the bed cover open.
