Except you know… That it’s not. A truck bed cover is on the exterior of the truck and can be often times folded over or removed entirely to expose the truck bed. The truck bed doesn’t extend to the interior of the car and is exclusively utility. Tonneau covers help with gas milage and theft prevention, they help things from blowing out of the truck bed. They have a ton of use.

Your livingroom is a garage with extra steps.

A cardio-vascilar surgen is a butcher with extra steps.

Heroin is just like marijuana with extra steps.

A tonneau cover still lets you load a pallet of something or a scoop of something in the back.

In most cases, yes. But it is better for carrying dirty stuff, and the canopy can be taken off of you need to carry something huge.

Still worse for most uses, plus utes and SUVs are way too big to be practical most of the time.
