I am planning to make the grand piano in my living room more mobile to make recording easier. I'd probably be moving it back and forth 10 ft or so over a hardwood floor about, say, a dozen times a year. My tuner/tech will provide and install. I have to decide between wheel dollies and a truck. Wheel dollies are cheaper and more attractive but don't support the piano as well. We don't really put on the dog much here at stately Rogers' manor, so looks aren't that big a deal. And the money is not enough to make a difference if a truck is really necessary. Question is: Is a truck dolly really necessary for this type of use?
