When I sold my 10,000 lb IH 500c bulldozer, the guy that moved it used a 14,000 lb GVWR trailer pulled by a one ton dually diesel from Dodge. Some of these new trucks have outrageous towing capacity. I followed the laod for the entire 30 minutes on back roads and then drove it off the trailer. Piece of cake. Beg, borrow, or steal a truck/trailer that is big enough.
Your half ton isn't even close.
The last post quoted 20% transfer of trailer weight to tongue weight which would be true for a gooseneck but 10-15% is ideal for a bumper pull.
Are you pretty sure it weighs 8000?
