A stock rocket called Duna Rover. Built with 45 of the finest parts, its root part is probeCoreOcto2.
Built in the VAB in KSP version 1.3.1.
A rover with a low profile and low center of mass. It won’t fit into a service bay, but it will easily fit inside a fairing or Mk3 Cargo Bay. It has a Small Inline Reaciton Wheel to help with stability at high speed. With a full battery there’s enough power to transmit each experiment all at once.
I originally built it for Duna, but it could be used anywhere there’s enough sunlight to keep it running and a relay antenna to control it.
