Frequently Asked Questions

  • What if the camper shell opening is larger than my truck window?

    If the shell opening is larger, the cowboy sleeper shell may not work. You’ll either need to modify the opening or consider a compression boot instead, which is more forgiving in such situations.

  • Does the boot stretch or compress?

    Yes, the accordion-style folds allow for both stretching and compression, ideal for movement and flex between vehicle sections.

  • How much cowboy sleeper shelldo I need?

    This material is sold by the foot. To determine how much cowboy sleeper shell you need, measure the full distance around your cab or window opening. Most full-size pickups need about 13–14 feet, while mini-trucks average around 10 feet.
