Hi Jamie, I am in the tear down now. I want to gut my van and start with a clean canvas. After 8 years of use I want to upgrade the while thing. As I already have 200K on the 7.3L I am debating if it is worth my time and $ to install 4x4. I too, will configure my van SMB like. As you mention, this will be a lighter and more economical version. Not to say it will look that way! Keep me posted on your build. Thanks- Boris
