Something new was added today.
Farm & Fleet had a three pack of ammo boxes and I sprung. One Fat .50 cal, a .50 cal, and a .40 cal all nested together like Russian dolls.
(sorry)
I went with the .50 cal as it didn't hang quite as low as the axle. Mounted with four 1/4" x 1" carriage bolts. A good place to put the tool roll a spare tubes.
The USFS chevron was just a goody I had laying around.
Now to figure out what to do with the other two boxes.
