I dont have a roll up, but instead have a Extang Trifecta. I like it alot more than a roll up. I can open up an open/close my bed in seconds, rather than going around and getting all of the snaps. It secures from the inside so I can lock the bed as well. There is nothing done permenent to my truck. If I remove the cover(less than a min.) from the truck you cant even tell I own it.
