Hi,
I’ve got a first Generation Colorado, 2011 Crew Cab with a 5.3 L V8. I’m looking at roof racks, and unfortunately, Chevy never intended this rig to have a permanent rack. I don’t want one of the temporary, ‘clamp’ style racks that hooks onto the door jam. I don’t like the temporary look and feel of it, plus it sits up too high once you place a safari style basket on top of the rails.
So, I’ve been searching for an aftermarket manufacturer for solutions, and came up with a big fat zero. However, on the second generation of Colorados, they offer a couple very acceptable solutions. One is made by Prinsu, they make a very cool looking roof rack that is meant to be drilled into the roof using 1/4” - 20 Plusnut inserts with 1/4” - 20 x 1 3/4” Hex Cap Screws and a 5/8” Aluminum Spacer. It runs about $700. +/- and it specifically says will only fit a second generation Colorado.
It’s nice, but I kept searching, then I found the Rhino-Rack RCCB1 Backbone Mounting System for $341. +/-. It also is designed for the second gen. Colorado, so, that was a bit disheartening. I then wondered what is the issue was, the contour of the Backbone or the length of the 2nd gen, cab, or IF the depth of the roof sheet metal is thinner on the first Gen? I contacted Rhino Rack and asked for the length of the backbones offered for the Colorado. They have two sizes, one for a extended cab 41.5” and another for a Crew Cab 51.66”
The contour probably won’t be an issue, so my only concern is the fitment, it’s designed to be drilled into the ditch (under the rubber piece that runs down the sides of the cab, that’s what the spacers are used for.) So, they agreed to sell me a set, and they will then ask for feedback on appearance and the installation process.
My question: How much clearance do I have under the metal? Will the 1/4 - 20 Plusnut insert fit deep enough? Does anyone have any experience with the clearances under the first layer of the roof? How far can I safely drill down?
I don’t want to be talked out of this, I just know there is a solution for a determined Colorado owner. However, I’m not fighting windmills, I know I need to plan and the proper know-how so, I’m convinced that you guys could offer any advice or thoughts about my project. I really need to know how thick the roof is under the ‘ditch.’ I’d really appreciate anyone with experience permanently mounting their roof rack on a first gen Colorado, plus pics if you have any to share.
Thanks to all that actually read this, I know it’s the type of thing that concerns nobody unless they are interested in roof racks for their rigs. Thank-you for your time and expertise.
All the Best,
JD
