Super Duty owners with the 6'9" bed get the Pro X15 1479101, a soft roll-up for 2017-2026 F-250 and F-350 trucks.
Aluminum cross-frame reinforcement under the fabric keeps rain, hail or snow from sagging into the bed. TruXedo tested the cover from -40 degrees F to 180 degrees F and in up to 95 percent humidity, so it is built for everything from Alaska to Florida.
Wind noise is what the Pro X15 is designed to remove. Its 5-layer, 120-grade textured RTxTechWeave top pulls tighter than traditional vinyl, so there is little to flutter at highway speed.
Expect an install of about 30 minutes to an hour. It clamps on, so nothing gets drilled, and the quick-release handle makes removal easy.
Do not drive with the cover partly open: either latch it closed or roll it fully up and strap it at the cab. Keep cargo from pressing against the fabric, and avoid conditioners containing silicone or petroleum.
