Mine is called "The Mule". Can't recall who made it. Has one 20" bike wheel and an aluminum frame six foot long. I replaced the metal spoked wheel with a plastic "Mag" wheel and dumped the innertube for a foam no-air tube from Wally. I love it. I use it regularly to carry everything from sacks of corn, the tree stand and stick ladder to the annual Buck or Doe. Dragging a deer is for the young[8D] The one wheel model is very maneuverable and the big wheel easily rolls over fallen logs. Whatever you get make make sure it has big wheels.
