Here's how I did my garage storage initially. I ended up buying a second Pro Angler and made a simple base like the one from this old forum posting. I made this rack when I first purchased my 2012 PA. I now store both PAs on the dual jet ski trailer (PVC rails) and the wooden storage racks are no longer used.
Here's how I will be storing my PA. Since I have the luxury of garage space, I decided to just build a rack to hold both the PA and the wife's Revo 11. Since it is taking up floor space in the garage, I decided to use the bottom area to store extra bags of mulch.
The center support is not attached to the 3 inch PVC so it allows the tubes to shift for a perfect fit. I had originally thought about making a storage cart the height of the truck tailgate, so that when I wanted to load/unload the PA from the truck, all I had to do was slide the PA on/off the cart. Then I could just roll the cart up under the Revo 11 or to the truck.
But for now this works fine. Tight lines!
