The reason these have no practical purpose is because all the things it does are done better with a lower bed. Having the bed so fucking high up makes it significantly harder to load and unload. If you’re actually carrying cargo that’s burdensome, you want a low bed, not one of these monstrosities.

Sure, they can do things, but the alternatives that are nearly gone from the market, and these replaced, did the work that a truck is “supposed” to do better. There isn’t a purpose behind making it bigger besides aesthetics to appeal to some people who need to feel bigger for whatever reason.
