Tonneau Cover for Trail Boss

21735 Views 11 Replies 6 Participants Last post by  chopuey
So I just learned today... at least from my local Truck Accessory installer, there are no existing Tonneau covers made to work with the sport bar on the Trail Boss.

I'm pretty disappointed and sure hope someone designs a cover soon.

I was about to ask you about that... I'm seriously considering the same model (and color) as yours, but the tonneau cover is kind of a big deal for me. :S
Check out this thread in the other Colorado forum. You will see what I did and what others have done.

Thanks @Woodys2718 , but I'm still waiting on them to authorize me to view the pics. :S

I did find a YouTube video of one that works with a LoRoll and minor mods... Since it's also a Laser Blue, I'm guessing that may be you. :) That works just about perfect. I'll check out the mods needed to make it fit as soon as I get into the other site.

Does yours flap at all at highway speed or when towing? I had something similar on a 1500 years ago that would occasionally get a bit carried away if the wind was right. :S

That isn't me in the youtube video,but that is the same Tonneau I purchased.

You will need to notch out the area where the Sports Bar clamps on to the bed rail.

It doesn't flap too bad at speed, there is some movement though.

Can you see photos on this site? I will attach some of the finished product, the notching of the rail and what the notch area looks like after I caulked the area.

No photos on the other site yet... it's looks like they have to manually activate new accounts. But what you posted here is perfect. I didn't realize the sport bar had clamps that wrapped around the bed rails. I'll probably be doing the same thing. Thanks!
I purchased the TonnoPro Lo-roll cover at the suggestion of folks in this post for my 2018 Colorado ZR2 Midnight Edition (short bed). It works great!

You do have to modify the rail a bit by cutting a notch in it, but I used a cutting wheel on a Dremmel tool and it worked just fine. One strong recommendation is to make sure your roll bar is flush with the truck rail before you start. You want the portion of the bar that hooks/wraps around the bed rail to be flush with the bed rail. On my truck the bar was not sitting flush with the bed rail, it stuck out a 1/4 to 1/2 inch or more. To pull it flush with the bed rail I used ratcheting tie downs wrapped around the bar and hooked underneath the truck. I just ratcheted until I pulled the roll bar flush with the side rails, and then I re-tightened the c-clamps holding the bar in place. Now the size/depth of the notch you need to cut in the cover rail is lessened, only requiring a notch in the top part of the rail.

That looks nice. Truxedo-lo-pro makes one for the Colorado with the sports bar. No modifications needed.

so the bracket from the roll bar doesn't need cut off.

Any more pictures. Like where the roll bar goes to the rail.
Thanks
