Gary, I had a sturdy X stand -- I put large wheels and some hooks to hang things on. The keyboard was covered with a moving blanket while in the car. I uncovered the keyboard, put it on the stand, put my wires on one hook and music on the other and off I went.

After a few trips I felt the idea was great but 2 1/2 inch wheels did not work well, although the rear wheels were secure ion one position and the front wheels moved for turns, it always felt like I was going to lose it. Larger wheel would do the job but they would not look good on the job.
