The lift comes off easily. Box the lift in a separate box. Also the main power/pump unit comes off easily, pack in in a nice heavy padded box. With the lift off and the power unit safely tucked away the big water reservoir is very light, and strong ABS, you can stuff it full of bottles and other bits. Make a box.
The Expert tank deserves a little TLC. The original box for these units shipped the unit without the lift attached, two poly end pieces in an ordinary box.
