I drove an F2 with tracks in the mud in rice. I don't want to ever squash creativity , but, one could not steer the thing with out RWA. The tracks are long and have a linear footprint and a mind of their own. Constant braking was needed and oh what a mess on the ends in turning. The setup for mud on a K2 is 23.1 X 26 drives with 11.00 - 16 F1s in rear . IF header size will allow. Also 18.4 X 26 with a snap on dual with no tires but rather a few metal lugs or paddles welded in makes an awesome mudder. Be ready to replace input shaft brgs every so often as well as having brakes up to snuff.
