How many of us are there? Owners of Dodge based RV's?

Eye, I can't comment on how mine was with the R-12 as the system was empty when I bought it. I went to my dad's shop to charge the system and what was left of the R-12 was not enough to charge it. So I did the convert. When is was 80 degrees out, after getting the house part cooled down with the roof air, the cab air kept the front ice cold and the hottest it got in the back was 78 after a 2 hour drive. I would say it was working pretty good.
