You need what's known as a moisture barrier between the external metal skin of the bus and your inside. One of the reasons spray foam is so popular is that in addition to providing insulation it also serves as a moisture barrier. If using other forms of insulation you'll need a corresponding barrier installed.
Other good tips are:
Avoid using propane heat sources which generate a lot of moisture.
Have good ventilation in place, especially near the shower.
Make sure if you're leaving the windows in that you have a mechanism to drain condensation from the windows so it doesn't leak in your walls. RV windows have a "weeping hole" for that moisture to drain out of, school bus windows do not.
