Winnebago Navion on 2016 Sprinter 3500 Chassis. The AC r134 pressures seem to fluctuate excessively and are not in the expected range for an outside temp/humidity of 80F/60%. Low pressure in Black and high pressure is Red. The graph shows the OFF condition with the engine not running. The On condition is with the engine at idle, max fan, 60F set point. The engine rpm was increased to 1800 for two minutes, then to idle, then to 1800, then to idle, then to off. The pressure seems to have a lot of variation at each stage. The pressures took a long time to equalize. What symptoms does this indicate? Thank you.

One thing I recently learned from a like situation, if a vehicle has dual ac zones, both zones need to be turned on to measure ac pressures, and also to fill freon.
Does your Winnebago have dual AC zones?
