This project might be of some use to B camper van owners who have a ladder at the back of the rig. I made it for a larger RV.
If you have wetsuits or beach towels etc., you need someplace to hang them and some sites don't let you attach anything to trees of fences or have a clothesline.
My wife suggested stacking the pickets this way when I was laying out different ways to use them. The cost of this was zero dollars to me as every single piece was something leftover from past projects. I used some SS threaded rod, L brackets, flat stock aluminum, c channel aluminum, PVC railing pickets, clear tubing, chrome look plastic trim, lock washers, nuts, lock nuts and wing nuts.
It provides about 23 feet of hanging space, folds flat for storage and takes up only 1 inch of space if placed at the bottom of a compartment or flat against the wall of a compartment. It seems strong enough for what I need and I can't imaging ever fully loading it. I used 10 pickets because that it what worked best with the spacing of the ladder rungs.
