Routing of drain hose for tonneau cover

[Cowboy Bill]

Just installed the BAKflip MX-4 EZ lift tonneau cover on my 2026 Ranger, I pulled off the large plastic plug at the bottom of the bed on the driver's side (there is on on the passenger side also). Looks like there is insulation behind it. Any suggestions as to where to route the drain hoses. I thinking of drilling a hole about half way up on the corner of the bed.

STOP! Put away the drill!

Sorry I am not near my truck right now to take a picture, but there are holes in the bedside that the plastic hose will easily insert. The downward angle of the hose isn't steep, but it flows water downhill. I'm a plumber, know a bit about downhill flow

Yes that's it. Feed the hose on, and excess water will drain on through.

I did not mount mine that way as I didn't like the idea of draining water into a place not exactly designed for it. The hoses also had to be fairly straight for a bit to get to that hole and I wanted something that drained more reliably. I was concerned about debris getting inside my bed sides where I couldn't clean them.

I drilled the two holes on each side where the rubber drain plugs here. They are covered by the bed spray, but they are the ovals down in the two bottom corners. These are rubber pieces designed to be drilled for drainage, you are not drilling your bed. I used a Christmas tree stepping bit to make the holes just barely big enough.

OP if you could use a photo of where these are I can post one.

I drilled into those plastic plugs and routed it there. The insulation you are seeing, should only be on the left side. It could actually be removed. (There are numerous threads about that.). I left the insulation there and drilled right through it. The hoses drain fine. I tried the higher holes mentioned above, but IMO, they weren't steep enough and gravity couldn't do its job.

Did mine the same way - but since I have a retractable it was my only choice.
