Tom is probably still there, he was in the season 8 finally (the article was before season 8 and says he moved), also his brother moved from ID to down teh road from Tom in MT. I doubt he's going anywhere.
Like Marty, but don't think I could handle his life, spending winters in the VERY cold running the trap line, alone (well with the camera guys). He is gone, told the show he wanted to spend the time on the trap line with his daughter. Maybe he'll come back after one year??
