What are the advantages of a body-on-frame structure?

Body strength is high, as the steel frame provides strong body rigidity, which also helps improve safety. More relevant information is as follows: 1. Vehicles with a body-on-frame structure have a rigid frame, also known as a chassis frame. In a body-on-frame structure, components such as the engine, part of the transmission system, and the body are mounted on the frame via suspension systems, and the frame is connected to the wheels through front and rear suspension systems. 2. The body-on-frame structure is relatively heavy, has a large mass, and is tall, generally used in trucks, buses, and off-road vehicles. Some high-end sedans also use this structure because it offers better stability and safety. Simply put, the suspension is not directly connected to the body but to the frame, and the body is then mounted on top of the frame.
I've always been a fan of body-on-frame construction because it's like giving the car a steel skeleton, making the entire structure incredibly sturdy. I've taken several off-road SUVs for a spin on muddy trails, and the body remains rock-solid, with the chassis independently bearing the weight, so the engine and other components don't strain the body. This means no matter how bumpy the ride, the body suffers minimal deformation and avoids creaking noises. It's also super convenient for modifications—the body can be detached separately for maintenance or upgrades. I remember sliding around in the snow once, and it absorbed impacts exceptionally well, making me feel much safer. This design also significantly boosts the vehicle's load capacity, easily handling construction materials or family luggage without worrying about the chassis collapsing. The only downside is slightly higher fuel consumption, but for me, durability and toughness outweigh everything else.
