The Jupiter first stage tank and 6K third stage tank are under-fueled by default. Propellant loading should be adjusted depend on the mission profile with reduced upper stage loading offset by increased first stage propellant and vice-versa.

Reference on propellant loading:
http://www.spacelaunchreport.com/jupiter7.html

" Propellant loading would vary depending on the mission type, with maximum upper stage loading for LEO missions and reduced loading for lunar or escape missions. Reduced upper stage propellant loads would be offset by increased first stage propellant loads, and vice-versa."
