Rent a little utility trailer, you won't even know it's back there. It won't fit inside the bed of the mini -not well - and you might end up breaking something. I've moved many, usually on a snowmobile trailer.
Load it on the trailer bottom down and backwards (so you're not pulling a parachute). Look at Rock Huggers pic, just flip it over. You'll need blocks or rimless tires to get it up off the deck so the posts aren't digging in. Pick up a set of 1" ratcheting straps to hold the bugger down. One strap near the back and one right over the door posts. Make sure the doors are strapped down also (nothing worse than one of your doors passing you on the highway).
I wouldn't take it apart unless you intended to do so anyhow. Even if it looks good from the outside, you'll be chasing rust and it'll turn into another restoration project.
