I slide mine (usually with some assistance from my wife) into a 1500# capacity dump cart, hook it behind my Farmall, and take it out back to shoot it. I just leave it in the cart when I shoot it. The drawbar mounted reciever trailer hitch it adjustable for height, so I can make some elevation adjustments by just bumping it up and down on the hitch a bit.
I also have a 4x8 foot utility trailer that tilts down to load a garden tractor or golf cart or ATV, etc... I guess if I ever took it someplace "on the road" that would be my first choice as the bed on my F350 dually is about 4 feet high and I don't really want to lift it that high.
You can find 2000# utility trailers new at Home Depot, etc for under $500. Used they should be in the $200 range.
