A horse trailer should make a good starter for what you want. They are
build to haul some heavy, concetrated, and spookable loads. (At least
your mill doesn't go nuts when it is placed next to a snake!)

You may find that the frame is not as robust as you would think: The
body on most of these is quite stiff, adds to the overall strength.

Registration should not be an issue: around here these have the
designation as "utility trailer", no way to tell what body is on it. The
ID marks are on the frame.

Many automobile insurance policies cover your vehicle and anything you
tow for liability. Check with your agent.

trying to think of a reasonable way to come up with something that can move
any of my machines (top weight about 2500#). I have a concept that I
want to
run by the "design review" board here :-)

My idea is to buy a junker 2-horse trailer, rip the body off it and build
a bed for it. My reasoning is there are tons of these around, and I do see
them occasionally for under $300. They have 2 axles, and many have electric
brakes. The frames are usually quite substantial, but the trailers are
pretty short. I don't want a long car-hauler type trailer, don't have room
for it, plus up here you pay by length when you go on a Washington State
ferry
boat, so shorter is better.

What do you guys think?
