Stay out of mud, you do drive through mud, drive straight as you can with minimal turning. Also, take it apart and wash it with a hose as soon as you are done. I mean take the track off, and unscrew the wheels and take them out and wash the mud out of them. You can do it but the more extreme you drive the more maintenance you will need to do. The sherman is quite amazing and nearly unstoppable. It took a 3 year old pushing it to break the rear idler off the hull when he got a rock stuck in it. Normal driving wont do that because the tank will stall before that must tension happens.
