Dale, assuming from your post, your dash A/C is not plumbed in at this time. If this is so, why not consider teeing the dash unit into the refrigerant system. Also, be sure the condenser is not lying flat. The outlet line on the condenser (line going to drier/expansion device/evaporator) must be lower than the discharge line coming coming from the compressor. This is so liquid refrigerant floods the evaporator core. I realize that your condenser will be rather small for the combination of evaporators, but it would certainly be worth a try. Generally speaking, I feel your compressor should not have a problem suppling enough refrigerant. I live in south Texas and regularly drive my B model Mack in 95-105 deg. temperatures and bright sun. I rigged my system up as explained above. I purchased my components from Danhards near Dallas. We probably have similar units under the dash, however I have 36" sleeper on my truck. Under the bed I mounted a medium sized box unit (A/C-heater) and ducted into the sleeper compartment. My condenser is about the same size as yours, with two electric fans mounted to it. For lack of space, I mounted my condenser vertically between the left frame rail and driveshaft under the sleeper. Locating the condenser in this position is not a good practice because it gets little or no ram air at highway speeds, but it does work acceptably well.
