I keep running this idea through my head - not that I'll ever get to it, but I'd like to do a 4x4 rat. A 4" clearance, suicide style front end RPU. I've been thinking about how to get the driveshaft past the motor. Haven't thought much about the suicide 4x4 idea yet, but I'm sure I will eventually. Crab steer would be something I've thought about too. I have too much idle brain time at my job...
