Fantastic video. To the point and informative. Recently added a 4020 to our stable, and she's got some LONG axle shafts (at least they seem like it). Im wanting to walk the stance out enough that I won't clip a gate or worse a building support with a shaft hanging out so far past the tires. Its either that, or duals... but I dont think I can justify the price of duals just for fun right now! lol
