Mun/Mimmus Rocket

Takes you to the Mun and back + Mimmus, along with landers if you want that spicy holiday away from the Kerb drama.

Slam out the solid boosters with maybe a 1/3 of the liquid; after they (solid) run out, detach them and slam on the liquid to get yourself into orbit. From there the rest is up to you, Cowboy.

Mods are graphical so shouldn't effect compatibility. Not sure if I used DLC content, may work if you don't own DLC but no promises.
