I appreciate all of the replies so far. I should have converted the system to 134a from the beginning, but didn't. I also failed to put in a drier with a sight glass, but have found in-line versions that can be added.
I bought an R-12 recycler 2years ago and have about 15 pounds of R-12 in a canister. I plan to evacuate the system and install the sight glass and replace an o-ring. No Freon will be lost into the air this way.
When I do repair work on automotive A/C systems I like to know the recommended factory specification for the amount needed, and re-charge that way using a refrigerant scale. I wondered if anyone knew the amount with this particular motorhome.
Currently the A/C doesn't put out very cold air, so I want to start over. The condenser is new, along with the compressor and drier. I also added an electric fan that has a switch on the dash.
