Traveling with the AT555

I am considering taking my AT555 to my doctor's office to check its calibration, which means, schlepping it on the train and wheeling it through the streets of Manhattan to my doctor's office and my own law office.  This will also give me the chance to take it to the office and take measurements there.  I would pack it up in the box it came in after engaging the travel lock, and move it using a portable luggage cart.  I suppose that the wear and tear will be no worse than what happened at the hands of UPS, but this makes me a little nervous.  Should I be?
