Well, I got it home.
The Cozy Cab IS the body. As in, you take the factory body/running boards off, replace it with the Cozy Cab, and then bolt the seat back on inside the cab.
We used a loader to get it into my Ranger... and my mud flaps dragged! 4 hours later, I'm trying to find a hill to back up to and a tree to chain it to so I can drive off and unload it. Because I have a 1k lb beast in the back of my truck, and no one to help unload it.
This ought to be fun.
Are cabs like this rare? The only ones I've seen that aren't a soft cab seem to bolt over the top of the body, and rest on the running boards, not replace the body.
