Childhood dream of turning pickup truck bed into swimming pool dashed by reality

To a child’s mind, the bed of a pickup truck is one of the most magical places in the world. Not only can you experience the incredible sensation, usually reserved for people with convertibles, of being outside while in a car, but the bed itself seems like a blank canvas for all sorts of fun stuff. Why not fill it with sand and enjoy a day at the beach while traveling? Maybe a couch or recliner could fit in there, drastically increasing the novelty of going to the grocery store? The possibilities seem endless until, like so many other previously exciting aspects of the world, you grow up to realize that actually none of these ideas are at all practical and life isn’t nearly as cool as you thought.
That is, unless you’re the group of modern day Icaruses who flew way too close to the sun by turning their pickup into a moving swimming pool and paid for their hubris in a completely predictable way.
