TC is totally top of the line for IFS, with the caddy kit (gen 1 i believe) my buddys 3rd gen pulled about 13" of clean travel in the front. He hammered that poor truck we jumped it way big at speeds quite a few times to this day its still holding up and runnin strong. He wasnt runnin 4wd witht the T-100 axles but the travel would be slightly less if he was like around 12" I think. I would say that with the kit and coilovers shock hoops and bumps you would be in around 4-5k. From what I have read though guys that keep the 4wd love it and say it wheels nice in the rocks and trails, and they can bomb in the desert too.
