Where did you learn this???
This question concerned my statement that I thought recirc was supposed to be used with a window cracked and for a limited time. I learned this from a number of statements in owners' manuals of cars I've owned. Anyhow, I understand the comments on the interior volume of the RV and I'll check the functioning of the doors and the shape of the vacuum lines. I was hoping that the cooling in recirc mode might be indicative of a specific problem as I've just spent a ton of money trying to get this thing fixed and it just does not work like it used to. For example, it is hot here (100+), however in similar conditions in the past the A/C has managed to blow cold air. Thanks to all.
