I got this cheap one on Amazon about a year ago.

North Mountain Soft Roll Up Truck... https://www.amazon.com/dp/B01N7KSD1Q?ref=ppx_pop_mob_ap_share

It’s totally fine. I park in the garage so can’t say if it’s very durable to lots of sun, but I use some 303 now and then for UV protection anyway. It doesn’t leak, it rolls up out of the way when I need the whole bed available. Easy install, all the sliding cleats are still functional. I did use some heavy duty Velcro to keep the clips from rattling against the back glass.
