Priced around $300 with the roll-up style and velcro. Supposedly better than the snap-style due to no stretching. Top mount, easy to install. Considering this and have two questions beyond any feedback from current owners. How do you know if your truck is the with or without bed cap style (not sure what bed caps are). Secondly, does anyone know where I can find them at lower than retail prices? Thanks in advance for any help.
