The Power Wagon shares its complete and legible instrumentation with the rest of the Ram lineup. All Power Wagons come with the Tire Pressure Monitoring System (TPMS) that we think is a really bad idea, even though it's mandated by federal law. You have to inflate the tires to 60 psi to keep the TPMS from flashing a warning light on the dash and sounding a chime. The Power Wagon has a light load switch that allows you to deflate the rear tires to 45 psi, but the fronts still have to be 60 psi. Not good.
