Kerbal Space Program - 4.6 tons to Tylo
For a challenge from The Destroyer to go as far as you can under five tons.
There were a few inefficiencies in this mission and a lot of xenon left over, plus for the challenge there was a no clipping rule. I suspect that just by iterating on this design, 150-200 kg can be shaved off. This is still the lightest Tylo return mission.
