I have a Lund Genesis soft tonneau, and really like it. I installed it in about 20 minutes, and like that I can just roll it up. I can lock my tailgate, so it’s somewhat secure. Yeah, somebody could peel it back and get an arm in, or use a knife and cut it, but I also don’t store high end electronics etc… in there. It has lifetime parts warranty as well. I accidentally busted one of the latches (completely my fault), and they sent me a new one that arrived in 2 days.
I like that I can roll it up and haul things. I had a fiberglass tonneau on a previous truck and I hated it. Taking it off was a huge PITA. I just did a self spray in bedliner since I have a cover on it, and just wanted some basic protection.
