Z Series Z Series : Chevy/GMC Colorado/Canyon March 20, 2015    Posted by: Tom The cap is 3/4th inch higher than the cab. I think that will cause a lot of air to be directed down between the two, and the fiberglass was not sanded very smooth before the finish was applied. 32767 Found This Review Helpful I Found This Review Helpful Overall 4.0 of 5 Fit: 4.0 of 5 Finish: 4.0 of 5 Function: 4.0 of 5 Performance: 4.0 of 5   DCU Cap A.R.E. Dcu Series DCU Series : Chevy/GMC Colorado/Canyon January 28, 2015    Posted by: Tom Generally the topper is well built and should be very functional. I purchased the " E-Lock " option, only to discover that the rear door still requires a key. I "assumed" that all doors (3) on the topper would be electronically controlled. Had I known only 2 of the 3 doors would operate keylessly I probably would not have spent the extra money for that option. The led lighting is good, but the wires between the doors and the control switches are poorly fastened, leaving an oversized loop at each location. I realize extra cable is required to enable the door lights to operate, but there is too much cable left in a loop, unfastened, that will surely get damaged either putting items in or takeing them out of the side compartments. 32767 Found This Review Helpful I Found This Review Helpful Overall 4.0 of 5 Fit: 3.5 of 5 Finish: 4.0 of 5 Function: 4.0 of 5 Performance: 3.8 of 5   Time will tell A.R.E.
