I just bought and moved a 7' valley downstairs to my basement. All we did as far as dissassembly was take the legs off. It was a straight shot from my door to the stairs, so it went smoothly. Do you have a corner or some other object to negotiate?

They can be moved easily this way. Remove the legs, and lay (tip) the table on it's side on a flat dolly. Then you can roll it anywhere. You will need help to load it on the back of a pick-up. I lay a piece of carpet on the tail gate and bed, and then put one end up and slide it in. Three strong guys can do it easily. One on each side and one in back. Going up and down stairs I like to lay the table on it's side (no legs of course), and slide it down or push it up the stairs. I've probably moved a hundred of them in my lifetime. No biggie.

P.S. A lift gate is the nuts!
