Early career mode... I tested a medium landing gear on escape trajectory out of the mun. I brought my monopropellant rover to the mun and rolled around, getting science data from
Highlands, Highland Craters, Midlands, Midland Craters, Canyons, East Farside Crater, Northwest Crater before the fuel ran out
It weighs 2.5 tons and I had to use the poodle engine to get it into orbit - and a kerbal trying to get mun orbit experience. I split the ship in mun orbit, flying the kerbal back home safely and crashing landing the rover with a small lander on the mun. Fuel ran out and I couldn't brake enough but in the last moment I ejected the rover and extended the wheels, and it landed intact while the lander was completely destroyed.
