Congratulations, well done and thank you.

I'm not sure what you're after. I guess it depends what you mean by stable. Rover below is 3 parts and 0.09 ton and is stable when SAS is on.

I have been working on my own challenge trying to complete the tech tree in RSS with as few launches so I already had a Tier 0 launch vehicle capable of reaching earth sized Kerbin orbit (over 9.4 km/s delta-v). I replaced the payload with a pair of detachable ships with the plan to use one for landing on Duna and returning to orbit and the other one for returning to Kerbin. This monstrosity, composed of 985 parts and a mass of 2393.72t, is based on the Minas Anor design used in Tier 0: 5528 science by allmhuran and relies on the joint stiffening included in 0.23.5. No mods were installed and no clipping was used. Turns out all i needed from the payload was parachutes. Score=(75)/((0-1)^2)=NaN
