RE: Does anyone drive a 6 or 8 wheeler Argo?
They do have a rough ride, especially if you are sitting in the back! The back space is better suited for carrying gear than extra passengers. They also are tough to amneuver when floating, and they feel tippy although I' ve never heard of one tipping over. They are also slow and a little on the noisy side.
If it wasn' t for the amphibious capabilities, I would buy a 4 wheeler before an Argo, but the Argo definitely is better suited for certain situations.
