underbelly storage

2015 Mountaineer 356tbf. Underbelly side walls have a carpet like cover and the roof is nothing but exposed aluminum bracing. Looking for tips and pics for attachments for fishing pole and other accessory storage. Basically anything to put fishing poles and other items off the floor of the underbelly storage and on the wall and roof of the underbelly storage. My 5th wheel has a large storage compartment but once you start shoving stuff in there its just a big mess. Just looking to do a better job of organizing things in the under belly storage.
