Can you convert a truck into an SUV by cutting the back of the cab and putting on a shell?

Answer 1

There's going to be more to it than that, truck frames are intended to have some flex between the cab and the bed, so you would have to add some more reinforcement there. And legally if you modify the frame you ought not sell the vehicle, just because doing so voids the factory warranty, so in the event of a collision you take full responsibility of the durability of the frame to withstand impact. Just something to be aware of. With that said I'm planning on doing the same, making the GMC equivalent of the Ford Excursion out of a one ton dually. Installing the interior creature comforts and running climate control, lighting, speakers, and whatever else you want back there will be the real money pit for you. And something else to keep in mind, the bed of the truck is not flat, making mounting things back there a bit more awkward, and the frame of the truck does not exactly lend itself to fold flat SUV seats. If you;re going for a full blown SUV conversion you'll have a bit of work ahead of you, or you can pay someone like Centurion to do it for you. Another option would be dropping a different engine in an SUV, like Duraburb does. There is a company that does the same with Ford vehicles, in southern Florida. Look around some more and decide what route you want to go.
