It concerns me leaving a dog in the camper with the A/C running, even if you have shore power. What if the A/C fails, or there is a shore power outage? Then the dog is locked in a camper with the windows closed and no A/C. I would rather leave him in the camper with a window open and the fantastic fan running. Then if the fan failed there would still at least be ventilation. Unless it is really hot the fantastic fan is enough. If it is too hot for that it's just too bad I can't leave him in the camper.
