The key is to get as much shade and air movement as possible. We have outside awnings on all of our windows plus mini-blinds inside. The awnings are deployed along with the patio awning, the mini-blinds are down and turned so the sun doesn't come in. Windows are open, all vents are up and the Fantastic fan in the front is set to exhaust. The Fantastic fan in the rear is set to suck in the air. We use small battery powered (Ryobi) fans to blow directly on us. The generator is used to charge the trailer batteries and the fan batteries in the evening while we fix dinner and watch TV until quiet time. We have a Honda 20001 which is very quiet.
We tell kids and guests they either stay in or out so the door stays closed as much as possible. No running in and out...
It's usually cooler outside than in the trailer so we spend most of our time outside in the shade with the portable fans blowing on us.
