I’m researching RV living and I apologize for my clueless question, just haven’t quite been able to find an answer so far... I’m worried about my dogs in the heat in an older class c RV. If I’m away shopping, doing laundry, etc., and they’re in the RV in a hot climate, what’s the best way to power the A/C to keep the cool and ensure it keeps working? Is there a way for a secondary power source to kick in automatically should the primary power source fail? What would be the best ways to handle this? Again, I’m sorry for the novice question, I’m just wading into the prospect and my dogs’ safety is a huge concern. I read about a situation where the power was tripped at an RV park, A/C stopped working and dogs perished in the heat... Thanks for reading!
