Yes. An open truck bed acts like a parachute at highway speeds. A tonneau cover reduces that aerodynamic drag, with independent tests showing 2–5% improvements in fuel economy. Hard and retractable covers tend to outperform soft covers in this regard since they create a completely sealed surface.
It depends on the cover type. Folding covers (soft and hard) fold toward the cab giving full access to the rear portion, or push completely forward for total bed access. Roll-up and retractable covers roll/retract to the cab end when fully opened. If you regularly haul tall or long cargo, a folding cover typically works best.
Most tonneau cover installations take 1–2 hours. We don't drill into your truck — covers mount with clamps or stake hole hardware. Same-day installation is available on most in-stock covers. Call us to confirm availability for your specific truck before booking.
