We have left our dogs in the RV for years.
Campgrounds don't have rules against leaving dogs in the RV. The have rules leaving dogs unattended OUTSIDE.
If your dogs bark a lot, you will have a problem wether you are there or not.
If you have young energetic dogs that bark often, you will generate complaints.
We always exercised our dogs before leaving. We leave the tv on and close all the shades so they are less likely to see kids on bikes, other dogs, etc.
We have left them in the RV with the genset running the ACs. If it's hot out we get the coach down in the 70's and only leave a few hours.
There are temp alarms on the market that will call your cell. Some phones have a feature called hands free auto answer so you can call and hear if the tv is still on meaning the power is good. iPhones do not have this feature unless you jailbreak.
We always use a Genturi stack when we run the genset.
