I don't mind Trail Mater, but I follow Matts OffRoad Recovery, which has trickled into Fab Rats, Mischief Maker and Robby Layton. It doesn't leave me much YouTube time to be a loyal watcher.
He seems to be a great guy, he's got an amazing rig and he's one hell of a driver. I believe he's done Hells Gate and The Escalator backwards. I'm sure those aren't the only obstacles he's done that on.
