Here in So Cal it can get pretty hot. I use a wire kennel for maximum air circulation. I use a reflective mesh tarp over the kennel for shade. Plenty of fresh water in the kennel and run the fan when there is no breeze. I plug a double female adapter into the charger with an input from the solar panel and an output to the fan. I kind of nurse the usage so the battery lasts for two days of a hunt test (I usually tent camp) and if/when I move the Jeep I plug the charger into a DC outlet to charge it from the alternator.
