Unverferth Gravity Wagon v1.0.0.0

I like playing with a older style equipment. Wanted a different gravity wagon so decided to convert this one. All credit goes to original modders, John Blard/ JMF. I reached out to JMF. A few folks in some discords asked me where I got these so I will put them up. These are error free I believe. Let me know if there are any issues.
