Service ceiling refers to the max height where an airplane can
maintain a specified rate of climb at max gross weight, but it's not
a limit. If you are patient, and especially if you are flying
light, you may be able to climb considerably higher.

Did they have, in effect, an air-lock? Or de-pressurize the whole

Neither. I'm 95% sure that the Caravan is an unpressurized
airplane, so everyone would need to use oxygen at high altitudes.
But there would be no concern about pressurization or anything like
an airlock.
