One of the clever little things we’ve discovered is that used cardboard boxes do a wonderful job keeping floors clean. So when we mop the truck down every day at the end of the day the first thing we do is break down some of our used boxes and place them on the floor at the front and back of the truck (as seen here). Then, as we walk in and out we don’t track any dirt into the truck (it all stays on the cardboard). The best thing about the cardboard is that it absorbs grease/oil. This keeps the floors clean and non-slippery.
