Question:
Will this fit a 2010 GMC Sierra Denali crew cab? Looking for dimensions of the cover to see if it will fit before I order this non refundable cover.

Hi Richard; the # EX89VR fits the Extang Trifecta 2.0 that is designed for the Toyota Tacoma. Do you have the 5-1/2' bed? It looks like that is what came with the crew cab. If that is correct, and you don't have the cargo management system, and you are replacing a cover for an Extang Trifecta 2.0, then you need the # EX92645-20. This replaces the tarp on the # EX92645
If you want measurements I can try to get them from Extang. I have never been able to get the measurements from them and I've asked on and off for several years. However, a customer was recently able to get them so maybe they have changed their silly policy to not give them out.
If you have a different bed length, and can let me know if you do or do not have the cargo management system, I would be happy to find the right replacement for you. Let me know in the comments below.

Hey Richard, did you find out if your Sierra has the 5-1/2' bed and no cargo management system? Once you confirm that, I can help make sure the replacement tarp you choose is the right one. Let me know what you found so we can get you the right fit.
