Gaylord Maxwell had a standard joke about tools that he used in his lectures at the Life On Wheels school he founded, to the effect that he never worried about carrying tools. Why? Because if something needed fixing while he was in a campground, he'd have tool-laden volunteers tripping all over themselves to help him, just to use the tools they had been packing around forever... :B
Gaylord died in 2008, unfortunately; he had the spark of life! Here's a link to a short video showing him at work, if you're interested:
