I was looking into getting a tonneau cover for my '01 KR. In a perfect world, I'd get a locking tonneau pre-painted in Charcoal Blue. But in reality that costs a bundle and if I had the need to haul anything, I'd have to remove it or be SOL. What does everyone think of the retractable/folding tonneaus? I like how they fit flush but I don't know how they work out with the railcaps on my bedliner (I assume they fit under them.) Does anyone have one installed themselves or any particular one to recommend? Any input is appreciated.
