[Fulltiming]

A previous owner had converted mine to 134A. Mine worked very rarely and when it did the air flow was not sufficient to really allow it to cool the front area well. I had a slow leak so it seemed every time I tried to use it, it was low on refrigerant. After recharging it, the air would blow cold then start warming up after a day or two. Newell told me to just run the generator and use the basement airs, it would be less expensive and work better. I suspect that the very long refrigerant lines, the relatively small AC compressor on the engine and the location of the evaporator all worked against it. I would not doubt that on my coach, it would cost thousands of dollars to make it reliable, ie replacing the compressor the evaporator, the expansion valve and the refrigerant lines. With both front airs on when driving, I really don't need the dash air. I use the dash air fans on vent to circulate the air and all is good. I can easily get too cold up front driving during the summer if I am not careful as the drivers side basement air blows down the valence panel and directly onto the driver.
