I have a 2013 Thor Daybreak, on a Ford F53 chassis.I just finished putting in the chassis condenser, I added 4 cans of Freon, 48oz, my pressures are at 20psi low and, 170 high, 70 deg ambient temp. It's blowing cold air inside, but, the pressure readings show that the system is low on Freon. I just can't believe I need to add more? I found a sticker with Freon capacity, but it is smudged, and unreadable. Does anyone know how much Freon this system holds?
