I used to work for one of the biggest tonneau manufacturers in the world and spent plenty of time as a test mule. I used to think trifolds were great, but I'll never own one again. They work well most of the time, but not as well as other options. I got a top-mount roll up probably 9 years ago and will absolutely never go back. It's just as quick to roll forward as a tri-fold but frees up the entire bed instead of less than 2/3. Just as quick to put back in place and only takes maybe 2 minutes more to remove entirely, but needs to be done far less often since it opens up the whole bed when rolled up. I don't like roll ups that mount inside the bed because they take up space and get beat up with cargo. Top mount like Truxedo Truxsport and Extang Express are great and some of the cheapest out there.
