A good AC tech would not have to know how much is required

X2.
The only time the total capacity # is required would be for a completely discharged system .
Top up; if necessary; would be done after a check with the proper gauges, and be a fraction of the total capacity.
Is the system is working at all ?

Thanks everyone!!
Thanks to all the replies, the wealth of knowledge here is amazing.
The coach has a leak and was empty of 134a. Filling it did not help though, but the AC posts further down gave me a wealth of things to check. Once again a new system to learn about, first time with AC trouble.

If the system was empty , two tests should have been run before any R134A was added .
1. Pressure tested with nitrogen , then check for leaks with a sniffer.
2. Vacuum test for an hour, removes the nitrogen and acts as a double check it no nitrogen leaks were found.
But a lot of shops choose to go the expensive route ( for the customer )on an empty system of installing the R134A with the leak detection dye .

From my Denso service manual, a Freightliner chassis holds 3.8lbs. It varies as to chassis build and OEM a/c unit.
