Roadcraft update is out. Fixed joystick steering and added more wheel support. Vehicles can be secured like cargo. Heavy dump truck still wees with every bump.
1 new vehicle transport, it's a longer Lynx with a trailer and retains the scanner. The other 3 are "search and rescue", just heavier trucks with winches. Since they are largely useless and the SAR scouts have jerry cans I think they'll serve as refueling trucks when that update happens.
