Some of the locking hitch pins can be broken with on good hit from a plain old claw hammer. I've done two of them that way.
One thing I've seen was a wheel chock for tandem axles the is put between the tires and tightened up and then it can be locked. One of the companies also made one for single axles that was like the boot police install on cars.
Go ahead, skin it! Skin that smoke wagon and see what happens...
I'll ride in on a sunny day, Sing you a song, steal your heart away Like a cowboy Hang my hat like I'm here for awhile Kick off my boots and drive you wild Like a cowboy Well baby you know I can't stay long You wake up, I'll be gone Until then I'll hold on Like a cowboy.
