Well, I decided to add a few more break-down options to my UTV target box. Rather than use a shorter box and have two piece legs I went with a little longer storage box that gave me extra room. With the extra space I can always add to the options. All the legs are the same length so they can interchange. Using this for now.... The bird holder had a little wiggle in it so I added some wingnut bolts to snug it up. All fits into this travel box. This is for airgun use. Target shooting uses more air so now I'm looking at making a better system to secure a spare fill tank to the UTV. Must be a simple removal set up.
