That is very unusual; normally the best settings for "hot and humid" is to set the thermostat for 10 degrees below outside air temp up to 100 degrees and leave it at 90 for temps above that. Set the blower on FAN or HIGH.
The air conditioner MUST cycle to not freeze up in high humidity so the water will drain and not freeze on the cold coils. Once the camper's interior air is "dry", you can walk the temp back down some.
