Anyone ever add freon to their Moho? Ford V-10 gasser. For some reason the AC stopped working about a year + back, it was under warranty then, but not now. Unfortunately had no time to deal with it.

So a few weeks ago I added a can. It was totally empty. It took a full can and the pressure was still low. That had to be a month ago.

The good news is today it was still up in pressure, the same as it was a month ago. So I tried to add more. Probably spent 45 minutes and still could not get the pressure to within the green area based on the temp today.

Think I got a bad refill can? Or are those autopart refill jobs not high enough pressure for a motorhome? or does it not matter, ac is ac?
