Will a Chevy suburban body fit on long bed truck frame?
No, a Chevy Suburban body will not fit on a long bed truck frame without significant and likely impractical modifications. The Suburban's frame and body are designed as a single unit, and the mounting points, dimensions, and suspension systems are completely different from those of a pickup truck. Even if you could somehow attach the Suburban body, the drivetrain, steering, and braking systems would be incompatible, requiring extensive and costly engineering solutions.
