Yep, here in Texas, other than the heavy rains, come middle of June, camping requires an A/C to be run from 9am to 7pm, preferably in concert with a dehumidifier so one doesn't feel clammy due to the humidity.
This is when the rig goes into (hopefully covered) storage until the weather breaks, which used to be early September, but has been as late as Thanksgiving in recent years.
Come fall, I know when camping season starts when I start seeing sewage hoses on the side of the road, or RVs with them dragging from the bumper.
