I would sure like some ideas where to store the spring bars when not hooked up. I have the Reese Strait-Line dual cam WD which pretty well takes the A frame out.
On my old trailer, I would store them in the front pass through (I had both a front and a back pass through). Now that I have a trailer with less outside storage I use a dedicated plastic storage container and put them in it, and slide it under the trailer. I've never worried about, nor had an issue with theft. If that were an issue, my solution might not work.
