Oshkosh is working in partnership with Ford. The ICE build uses a Ford drive train, and there's a connection to the Ford Transit. This is how most contract commercial vehicles are built for the US markets, take a cutaway truck/van from usually Ford or GM, and put the needed body on it. Sometimes even the cutaway cab is too much, there's often a chassis+engine only package, and sometimes a custom chassis is needed. GM had entered the procurement process, but left early on. Rivian had no track record when the procurement process began. No argument that the process is long, and probably has problems, but I don't think it's strange that Oshkosh made it through the process.
