Based on the replies and suggestions in this thread, I think my money would some be better spent on some type of temperature alarm that works with our cell phones. Those people who lost their dogs to the heat that I mentioned earlier in the thread actually had a temperature alarm that worked on a radio signal. They had gone out of range. Don't ask me what type or frequency it worked on. I never got many details about it.
One thing I do when I leave the dogs in the RV is to set up my Fan-Tastic fan in the bathroom to turn on when the temperature gets to the point where the AC is obviously no longer working.
