A/C question

Summer is right around the bend over here. Its time for me to take a look at the A/C system. The good news is it works. I have a Havasu trip next month. Can you guys tell me what the pressures should be on the LP and HP side while it's operating. I have a set of gauges. It has not froze me yet so it might need a charge.

I have not tested it yet. Where can I find a chart? Is there a chart for SD trucks or or they generic?

Thanks, that should work
I drove the tuck after work today.
I places a temp gauge in the AC vent, it measured 31C before I turned on the AC. I put it on AC with the fan on the 2nd setting. The vent temp drops to 7C on the street and in stop and go traffic..
