It took nearly a million dollars, but I finally brought a large five-man refueling rover to the Mun - demonstration video coming later on YouTube.

Capable of refueling even the largest of Mun landers, this bad boy can mine ore anywhere and dock with anything. Sure, it may not have the science lab on board, but it's a refueling truck; it does carry some scientific instruments of its own, though. Either way, this truck is built for maximum specialized performance.
Here are some numbers about the rover itself that I think you'll find very useful.
Electric Charge: 21,235
Oxidizer capacity: 3,520
Liquid Fuel capacity: 2,880
Monopropellant capacity: 760
Ore capacity: 1500
Any questions/concerns/comments?
