Just purchased 2022 Sierra 1500 Denali with factory spray on liner. Picking it up in a couple weeks. Buying a Retrax tonneau cover for the back. Instructions say to put drain tubes out the holes in the bed. Seen some videos of people who drill into the sidewalls. Are there any drain holes still visible with the sprayed on liner? Also might there be some on the floor up front to put the 3/8” hose into? Not sure about having to drill. Thanks for any help.

There are places pre drilled for the drain hoses, I placed the hoses on my 2022 Denali when installing the tri fold cover.
Where in the bed are they. I have a factory sprayed in bed liner and I don’t see them. ThanksThere are places pre drilled for the drain hoses, I placed the hoses on my 2022 Denali when installing the tri fold cover.
My 2022 Sierra Denali 3500HD has the spray in liner. The drain holes are on the front of the bed 2/3 the way up the wall. One one each side of the wall. There is a rubber pluf about the size of a quarter. take them out and drill a hole in each on for your drain hose. Replace the plug and you are good to go.Just purchased 2022 Sierra 1500 Denali with factory spray on liner. Picking it up in a couple weeks. Buying a Retrax tonneau cover for the back.
