Ride quality...pretty good. Takes lots of weight to balance these and it's still not perfect. Road noise....fairly minimal all the way up to 80. Fitment...very slight rub on the factory splash guard at full lock to the left when in reverse....but no issues full lock on the right. Fuel economy.....this will leave a mark. Normally about 21mpg at 77. Took a trip to Florida on I-95. Averaged 15.4 mpg at 77.
For some reason I cannot upload a PDF here but Google this PI0564K It will pull up on the NTSB site and you can download the PDF there. It will give you all repair instructions to basically replace all the wax on your frame. Unless you completely degrease your frame anything you add to it will fall off.
Well... You're not supposed to undercoat a waxed frame unless you completely strip and paint it. Any kind of petroleum based product will soften and remove the coating. GM does have recommended repair procedures.
Check a couple of things...first your USB cord. Believe it or not some cords are just crap with these trucks. Second try moving your USB port assembly slightly while you're plugged in. Mine is bad and forces a restart everytime along with alerts for missing SD card etc.
Agreed...but if used within their parameters...it works well most of the time. Love it when stuck in bumper to bumper traffic. Just kick back relax and the truck will idle along with no issues.
