International-market GM pickup trucks, specifically the Chevrolet Colorado (which is also known as the S10 in some countries), are available from the factory with roof rails that enable the use of a roof rack or roof-mounted cargo carrier. By comparison, American-market models do not offer roof rails, even as an option. Not only does this seem like a pretty unfair deal, but the topic itself is worthy of dialogue.
Now we cannot speak for everyone, but it’s probably safe to say that most people who opt for a Chevy or GMC pickup will carry and haul cargo or recreational equipment at some point in time. After all, that’s the entire point of having a pickup truck – an automobile capable of hauling people and their cargo, at the same time.
Having roof rails (the longitudinal units mounted on the roof of the cab) as part of the vehicle enables one to mount a roof rack on the truck, thereby enabling owners to carry various items on the roof, such as bikes, skis, snowboards, paddle boards, surf boards, and other kinds of cargo carriers. Not only does this help keep the aforementioned items secure and steady during long drives (which is rather difficult to achieve in the bed of a pickup truck, as things tend to slip and slide around), but it also frees up a significant amount of space in the cab and bed for other things… things that are better-suited to be placed in either the cab or the bed to begin with.
We’d argue that having a roof roof rack on a pickup truck is the equivalent of having another box/bed, one that acts as a sturdy platform for items that won’t rattle or slide around during transport. But here’s the unfortunate part: not a single GM pickup truck in North America offers roof rails straight the factory… not even as an option. The only way one can get them on your truck is to find an aftermarket set.
Even if you did find a set of aftermarket longitudinal roof rails in hopes of bolting to them a roof rack or cargo carrier of some sort, installing the roof rails is less than an ideal proposition, since you would typically have to drill holes into the roof of your truck – a cringe-worthy endeavor, to say the least. Moreover, drilling is not even an option for roughly half of the market who lease their GM pickup trucks, for obvious reasons.
So, it seems like a no-brainer to conclude that GM pickup trucks should offer roof rails, at least as an option, from the factory.
