Truck Bed holes

[Frasierts]

Newbie question here but can someone tell me what these are in the 2020 GMC Sierra truck bed?  Is there an accessory that fits in for an additional tie down?  I appreciate the responses!

One of the main things I’ve seen that used for is for the drain hose for tonneau covers.

They are in front of the grab handle spot so I'm assuming they are to do with adding a ladder rack or something. To help lock the post in type of deal

Does anyone have a diagram of the holes in the front panel of the bed? Not the rails but the front panel for drain tubes on a retrax cover

The hole is used for bolting in anything that slides into the bedrail hole.

 I found a smaller diameter tubing that fit into the pre-existing drain holes in the bed floor. The new tubing slips inside the stock larger tubing that comes with the Retrax cover. The problem with the side or front holes are they are higher than the drain tubes on the Retrax cover as well as the canister for it covers all these locations.

That hole is perfect for drain tubes from REALTRUCK Hard Trifold cover. No need to drill a 5/8 hole mentioned in instructions. I'll add pics later
