I need help with importing a large .obj file as a solid body (or even surface body)

I'm running SWX 2019 SP5. I bought a model of a military truck thinking that I would be able to convert to a solid body. Even a surface body would suit my purpose. When I try to import it I get the error that it has too many surfaces. It will only open in Solidworks as a graphics body.

Any suggestions, or did I just waste \$200?
