if i had the money, and the terrain for rockcrawling, i'd love to have the sami as well as my tracker... that way, i'd have a mudder (tracker), and a rockcrawler (sami)... i just see a tracker, with the IFS, going semi-full speed and taking an awesome dive into a mud puddle, and hydroplaning and skipping across the top like a flat rock on a smooth pond... likewise, the sami, with the option of a 5" SPOA system, i can just imagine pulling one wheel up the side of a boulder, while the other 3 are still on the ground, or barely off the ground... i just don't see a trackick being an avid rockcrawler, and i don't see a sami being a mudder.... that's just my opinion.. seems like each has its own place, ya know?
