I strongly suggest, you go to the controls and assign new controls for rover steering (I use numpad 4,5,6 and 8), so your commandpod does not apply torque when you try to drive your rover. Yeah, I also needed some time to wrap my head around rover construction. But here are a few sceenshots that might help you. An early, compact design with rcs An unmanned long range rover, you can build a chassis with Modular Girder Segments An manned long range rover, I used a Mk 1 Lander Can as core and a command seat for driving. This way the navball point in the actual direction you are driving. Two lightwight rovers - they basically consist out of 2 M-1x1 Structural Panel, four wheels, one rtg, two batteries and command seat.
