    Default Who makes tonneau covers for GM ?

    Does anyone know who makes the covers for GM ? The kind of look like Advantage the way they latch. I bought an Extang but so far two of them dont fit right. I'd like to buy the one from GM but theyre a little pricey and it says you need to have the bed rail protectors. I put this post on another site also. Somebody out there must know !

    I put an Undercover Tonneau on my 2011 Silverado. It fits great and I have had no problems with it.

    I have the GM tri-fold and I love it. I do not have bed rails and it just covers the beds stake holes when on correctly. Yes they are pricey, but I got mine from a member and he hooked me up!

    That's odd you say that about the Extang, as members here typically have good things to say about them. I had the Extang Revolution, the model that is level with the bed rails, but then switched it out for the Truxedo that sits on top of bed rails (I needed the extra height to fit a camping gear box in the bed and would still be able to cover). The Extang fit like a glove and I liked the fact that it did not have velcro or snaps to hold it down. I also like my Truxedo as it fits great and has held up well over time.

    You sent a reply on my original post about Extang covers. I understand you've installed a bunch of these. Send me a PM with your email and I'll send you the same group of pictures that I sent Extang. The customer service guy that Ive been dealing with doesnt know why but even he thinks it doesnt look right .
    The only way the front rail corners sit right on the bed rail is when you put the thicker foam under them Then it raises the rails even higher. I followed the instructions that come in the box to the letter and the rear rail sits way too high if you ask me. I only did one side because I didnt have enough extra foam pieces to do both. I called Extang and they said I shouldnt need all the extra foam to begin with. Thats when they wanted to see what I was working with.
    I hope you guys understand, Im not some bonehead thats never owned a truck before. Ive had these covers on quite a few other trucks in the past and NEVER had any problems.

    That wasn't the intent of our responses at all (you being a "bonehead"). Sorry if it came across that way. It was more in the sense that it is surprising, as these are straight forward, easy to install, great quality, and I have never of them not fitting properly (doesn't mean it hasn't happened though). Either you got a couple of bad ones, your truck bed could be little off, or something else of an exception is at play here.

    I guess to answer your question directly, no I do not know who makes them for GM but if you are looking for good alternatives that are less expensive, as you elude to, then I would recommend a Truxedo, based on personal experience and what I have heard about them from other members.

    I didnt feel like anyone was questioning my abilities but we all know there are some folks out there that will never own a wrench. And there are also guys out there that own them but dont know what theyre used for ! Ive been driving 4x4s since the mid 70s. Long before it became the "fashionable" thing to drive. I usually put the same stuff on each truck that I own. Over the years Ive calmed down a lot as far as spending money on daily drivers. Especially since the newer trucks come with so many options. I would rather spend the money on a part for my car instead of a set of aftermarket rims or lights for my truck. But the cover on the bed is a must !

    Yep, I agree with you about bed covers..that's why when I could no longer use my Extang due to its low profile, I had to find something that worked for my needs in a more utilitarian fashion; a bed cover is a must for me as well and could not go without having one. I definitely feel you there.

    Good luck with your search!!

    On the subject of Tonneau Covers has anyone tried or have the BakFlip G2 covers? I like the idea of being able to lock it as well as the hard top being sturdy. Please let me know of your experience on this one or any alternatives that are better.
