We used threaded hooks in our front compartment.
If spaced right, you can hang 3 poles from the hooks on the slanted front wall. Just look for staples and you will find studs to thread the hooks into.
I did the same with a larger hook on the door side. Hangs the jack crank and awning bar up out of the way.
If you need more, maybe put 3 rods on each side, or hang them from the wood framing above (just watch so you don't hang from part of framing that is the lift-up bed).
