I am hoping someone has tried a 7'6" x 27" high plow with success on the 2015-2019 Colorado.
Please let me know if it worked out ok or was a mistake going that big.
Thanks

 

I'd consult the owner's manual as to whether a snowplow should even be mounted on such a light truck. Generally speaking, the lowest grade truck should be a 2500 or greater to use a plow. Snow plows should not be used on light duty trucks. Not saying people haven't done it, but I would imagine such use would void any warranty.
