We have moved a 12" long Gammill 2x. The first time we took apart (rollers, leg assembly & rollers) all the components and rented a trailer long enough. At the end we had 6 (4 lifting & 2 positioning the legs) persons to move it up the stairs & put it back together. The table weighs a lot & was the key to moving it d/t length, weight & width. The table doesn't break down.
The second time we removed the head and transported it in the car. It took 4 men to move it out of the double doors of the house, down the stairs, to the driveway & into the trailer. The table fit assembled into a stock trailer and we'd added wheels. Is was only necessary to take it off the trailer and it stayed in the garage. We used car jacks to raise it for leveling.
We were much more organized the second time.
