As for speed records, not to brag or anything but I believe I am the current record holder for Highest sustained highway speed in an AD 1-ton (3804 class). If you want to go for a new record, Charlie and I will be happy to fly chase for ya. Record currently stands at 75 MPH.

Best part is, I think the first approach to 75 was without floors or a hood he was that excited!! His grin is still priceless.
