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

The pressures can vary quite a lot depending on temperature. Generally speaking the low side will be 35-45 psi and high side 150-200. That said the best way is to evacuate the system and weigh in the correct amount usally stated on the sticker under the hood.
