Watch that sliding stuff! I lost the stairwell courtesy light to a cast iron hand pump that slid from the rear of the bus up to the front door stairwell at a quick (but not sudden) stop. Also broke the cast iron pump, which was going to be the backup waterpump for my bathroom.
The biggest reason that I don't drive my bus much is that I have not completed making all of the fixtures (shelves, cabinets, etc.) secure against the motion of travel. That and the fact that it won't go more than 50MPH. And the fact that diesel is $2.40/gallon and I get 8 mpg.
But the sliding/shifting/falling issue is a biggie.
