The Highway Flap Trap: Why Cheap Vinyl Covers Destroy Themselves at 70 MPH
Share
You just bought a pre-owned 2014–2018 Chevy Silverado 1500. You want to keep the snow and rain out of the bed, but you don't want to drop a thousand dollars on a heavy aluminum cover. So, you find a $150 generic "snap-on" vinyl cover online and bolt it to your truck.
It looks decent in the driveway. But the exact second you hit 70 MPH on the highway, you hear it.
Smack. Slap. Smack.
You look in your rearview mirror and see the cheap vinyl aggressively billowing up like a parachute, violently slamming against the aluminum crossbars. A few months later, the summer heat stretches the cheap material out permanently. By winter, it has shrunk so badly that you can't even force the snaps closed.
You just fell directly into the Highway Flap Trap.
A soft cover is a fantastic, budget-friendly way to protect your cargo, but only if it stays tight. Cheap vinyl without a mechanical tensioning system will stretch, flap, and inevitably tear itself apart under aerodynamic drag.
You don't have to deal with the noise, and you don't have to fight with frozen snaps. You just need automatic tension control.
In this guide, we explain exactly how premium exterior engineers at Truxedo and Access utilize spring-loaded tension plungers to keep your cover drum-tight in any weather. We'll show you why industrial Velcro is mandatory for winter, how to measure your bed correctly, and why stepping up to a matte black canvas cover completely changes the look of your truck.

Frequently Asked Questions (Soft Roll-Up Covers)
Will a soft roll-up cover violently flap on the highway?
Not if it has automatic tension control.
Cheap internet covers use fixed snaps or weak Velcro, which allows the wind to lift the vinyl, creating a loud, annoying slapping sound at 70 MPH. Premium covers from Truxedo and Access feature spring-loaded tensioners inside the rear header. This actively pulls the cover drum-tight, creating a smooth, aerodynamic surface that completely eliminates highway flapping.
Can someone easily break into my truck bed if I have a soft cover?
Yes. We want to be completely honest with you.
While a soft roll-up cover locks securely at the tailgate (meaning someone cannot simply open it if your Silverado's tailgate is locked), the material itself is just canvas or vinyl. A determined thief can cut through it in three seconds with a pocket knife. If you live in a high-crime area or carry extremely expensive tools overnight, we highly recommend upgrading to a BAKFlip Hard Folding cover instead.
Are these covers hard to roll up in freezing winter weather?
No, industrial Velcro solves this.
Old-school "snap" covers are a nightmare in the winter because the vinyl shrinks, making it physically impossible to stretch the cover over the snaps. Truxedo and Access use high-tack, industrial hook-and-loop fasteners down the entire length of the rails. No matter how cold it gets, you simply roll the cover out and press it down into the track.
Stop the flapping. Block the weather.
