Why is the back of my truck higher than the front?
In general, pickup trucks are one, if not the most versatile vehicle available in the market. Ford first invented them due to farmers' need in the early 20th century for an industrial replacement of work animals.
The designs of pickup trucks are heavily geared towards utility, versatility, and capability. this is why their end is higher than their front. They are designated to bear the weight of cargo being placed on their bed without compromising performance while driving.
This is also for towing purposes. As we all know, the best vehicle for a towing job is a pickup. When a pickup truck tows something heavy, the level of the frame will change because of the height of the hitch receiver. This will cause the truck to squat slowly.
Without the design, the squat of the truck would be exaggerated towards the back, thus lifting the front of the pickup. This could be a problem as the cab may tip over, especially while driving.
Another reason why the front of your truck is lower is for aerodynamics. The truck slices through the air more efficiently by having a lower front, and its mass is more down to the ground. This makes it safe from the wind lifting the front end of your truck while driving at high speeds.
It makes it easy for the vehicle to go over huge puddles, river crossings, and rocks without getting damaged, compared to an average vehicle like a sedan if it were to pass through these terrains.
