I did some years back. They are big enough to require truck freight. Do make sure you get in writing how long the trip will take, Yellow Freight took 7 months to ship them back from Maggie to CA but only two weeks to get to Maggie.
Do box them as if you expect brutal handling. They drove a fork lift through mine and they had to go back again to get rebuilt.
Do call Maggie and ask them what they recommend for a shipper, they would know what works and what doesn't. Frankly, if they are within 500 miles from you, I call it ROAD TRIP!!!!
