As I was going through my photo's, I ran into these from last April. The first is a regular ST4 loaded with plywood on the roof and logs on a drag. The second is Larry's (Roughwoods) TrackMaster powered by a 1.6L Toyota with a load of walls and insulation. The third is an unfortunate episode with the tire speed exceeding ST4 speed. If you look close you can see the tire is en-tirely gone.
