Pets left alone in RV at campground?

We raised our two dogs from the puppy stage to full grown, camping and travelling in various vehicles. We also use cameras with sound so we can hear if the dogs bark and also speak to them. We had a temp and humidity monitor as well. The camera was tied into our inverter so if there was a power failure we would know. The Verizon mi-fi was battery back up which was connected to the camera and temp stik. Over the thousands of miles we have travelled and the number of cg's we have stayed we never had an issue with the dogs or the cg mgmt.

I would not leave the windows open, rather cut on the a/c or just the fan if it is cool enough and leave a radio on. Leaving the window open will almost be sure to get them barking at something. Bottom line know your dog, prepare and always monitor.
