I have the Tonno Pro tri-fold cover. I love the concept of the Tri-fold and so far it is holding up okay. I have had it for almost two years and it is showing signs of wear, I hope I can get another year or two out of it. One of the straps that holds it in place when open broke last weekend so I only have one left. It takes me about a minute to take it completely off and on so if I need to use the bed for larger items I can. This cover has gotten a lot of use as I take it off weekly for runs to the dump. I feel you get what you pay for when it comes to these kind of covers. Mine was around $200 bucks which is on the cheap side for a tri-fold. I will probably look for a higher brand name when I get the next cover.
