Cooking while driving???

I have left a full glass of juice on the counter one time, in a fifth wheel trailer. Put it by the door to get when I went out to drive, but forgot to grab it. 500 miles later we stopped, and went back in. Fist thing I saw was that glass, sitting in the same spot, not a drop spilled!

Our Bluebird Motorhome now rides even smoother than the 5th wheel.
