To play devils advocate for some trucks, in some situations they really are needed. I happen to live in an area with lots of dirt roads, and in the spring we have “mud season” where the roads just turn to soup. I have had it where the ruts are so deep (1-2 feet) that the only thing that could make it is a stupidly large truck.
That being said, the vast majority of people don’t live on or near dirt roads and never have a need for a truck this big.
