BAK Revolver X4s Far Superior to Peragon

I previously had a BakFlip for my 2019 RAM, and when I got my 2023, marketing from Peragon convinced me to switch brands. That was a mistake. Although the Peragon permits full access to the bed when the cover is removed, they fail to mention in marketing materials that if your load contents shift to the front during travel, you won't be able to open the cover until you shift them rearward. Also, the folding design permits any standing water on the cover to drop into the bed. when opened. By contrast, the X4s is now an even better design than the BAKflip. I can't quite use all of the truck bed with the cover rolled up, but it's enough to load my dirt bike and close the tailgate on a 6' 4" bed. BAK has obviously done a better job of thinking before building.
