I think the dash air in my diesel pusher need a shot of r134a. what are the optimum pressures on the low and high side? thanks

There are cans of R134a that include oil, sealant, and freon. The 12 ounces on the can will not be 12 ounces of freon.
I finished a re-charge of my system yesterday. I used a real set of gauges and charts available for my chassis.
I saw refill cans in the auto parts store that have the gauge with the green zone and psi up to 55. This will be the suction pressure - the blue hose. R134a systems will not let you connect the hoses incorrectly (fittings are sized differently) unless you are using old R12 gauges and R12 to R134a adapters and are color blind.
