Fishing rod holder

You could build a pole holder out of pvc similar to how they do it for kayak fishing. And have that slip down into the holes in the bed.

example

We use ice fishing rods when we brook trout fish. Works great for tighter areas. Typically the cork of the rod is behind the lock n ride handle. Drivers side is, wife’s side isn’t 😜 Used some solid foam behind the reels to prevent rattling.
