It’s a simple thing but very useful as the parking brake cable on a bus is very long and can sometimes give way enough for the vehicle to start rolling. Call me paranoid, my dad’s bus once rolled down the driveway into a tree, and yes I park in gear. We often head to the beach in our ’74 Westfalia to enjoy an afternoon by the sea. I love looking at all the variations of beach wood, some natural or in this case man made. This block struck me as being the perfect shape and size to become a VW bus wheel chock that would fit easily behind the driver’s seat. I gave it a dash of orange paint from a rattle can and made a grip from the remains of some old lawn chair webbing, and voila!
