I am not sure the charge value is very readable on my 2013 ACE 30.1 either, but it looks like 1.75 pounds (picture attached). There is also a link I quickly found regarding Evans Tempcon recommended charge specs for various RV vehicles .....check the index for charge specs. I don't know how dated this document is or even if it is applicable to our coaches; just grabbed it for you. If you find out a confirmed alternate value post it. Good luck.
