When in works 100%, I never had one do much more than cool whoever is in the two front seats while driving. I got tired of recharging mine so I pulled it to save weight and get better air flow to the radiator. On a real hot days run, I run the generator and rooftop ac. Otherwise I just run the dash control on vent to keep cooler.
I also added a duct from the grill to the vent inlet to get cooler air coming in. Without it the vent just opens to the wheel well on the passenger side, so it picks up some engine heat, and any engine aromas the old motor emits.
Do not take life too seriously.
You will never get out of it alive.
