Easily removable bed covers?

That does look simple. How does it hold up snow? Does it sag much? Do you have to clear it right aay?

I have a tri-fold tonno cover. you take cover out of box and lay it on bed with front aligned with front of bed. rotate down front clamps and tighten with hands. fold cover back to cover complete bed, fold down and tighten 2 rear clamps with hands. close tailgate and your done.
