We leave our dog in our coach with AC on when we sightsee. Our only concern is a power failure. I use a free app called Presence. You need an extra cell phone connected to wifi or activated to use carrier data. Presence will allow you to monitor video and audio remotely. We leave one phone in the coach pointed towards a thermometer so we can monitor temp changes. We can also hear the AC running and hear if our dog is barking. Leave the phone in the coach plugged into a charger as the video feature uses a lot of battery power.Try it.
