Presenting; Munotaur V-K(erbal) mk5 With this I decided to test Kerbal's integrity by designing the US Minotaur V rocket as near as I could with Kerbal parts. The US Minotaur V can take large payloads into orbit or take small ones to orbit the moon. Thus, Munotaur had to be capable of the same. After much tweaking (mk5, ironically enough) I managed to get it to work! The only design change I had to make was the solid boosters. The Minotaur V uses 3 stages of solid rocket boosters to get off the ground, then two stages of motors for orbit. Kerbal's solid rocket boosters just weren't up to the task in three stages, there was too much weight, so I compromised and grouped 5 solid rocket boosters into one stage on the Munotaur V. This was tested, to orbit around the mun, with MechJeb. The fuel toes the line on each stage, you lose a tiny bit of acceleration between stage 2 and 3 if you don't separate quick enough, but overall it does work with a tiny bit of fuel remaining at the end. Bring the rocket up into a 100km orbit around Kerbin then head on intercept towards the Mun from there. Once you're in range it should be a short burn into orbit.
