I tinkered on this a little today after work. I cut a 6" section of rubber garden hose and a slightly shorter piece of 1/2" dowel rod. I drilled a hole through the dowel rod just large enough to push a length of paracord through. I used a hole punch to pop a hole in the side of the garden hose. I strung the paracord through the garden hose hole and the dowel rod and pushed the dowel into the garden hose. I bought a Cord-Lock from Farm and Fleet on my way home from work.
I slipped the paracord through the cord-lock and then knotted the ends of the paracord so the cord-lock can't come off. This is what it looks like:
To use, just drop the end through the thing you want secured:
Loop the hose through the paracord:
Drop the garden hose section into the tailgate gap and slide the cord-lock up the paracord until the garden hose section is just about an inch or two under the bed.
When you shut the tailgate, that gap will significantly shrink and the section of hose will be trapped, tying your stroller (or in my case creeper) back against the tailgate.
