Despite the numerous advantages, there are challenges associated with tube chassis design. For one, the welding process requires precision and expert craftsmanship. Poor welding techniques can compromise the integrity of the chassis, leading to potential failures under stress. Additionally, while tube chassis are suitable for many applications, they may not be ideal for vehicles designed for everyday use, where comfort and aesthetics play a more significant role.

In contrast, unibody construction integrates the frame and body into a single unit. This design is commonly found in sedans, crossovers, and many modern vehicles. The unibody structure typically provides better fuel efficiency and handling characteristics due to its lighter weight and improved rigidity. However, repairing a unibody vehicle may be more complicated, as damage to the body can compromise the frame's integrity.
