The big caveat to any of these designs, including Budward's, is many jurisdictions have fines for leaving a vehicle on but unattended.

 

Downsides are the need for a dedicated remote, and it would add some additional start cycles to the starter and engine.  Not something you would want to use for hours at a time UNLESS the vehicle was a hybrid OR one of the newer non-hybrid models which shuts off at traffic lights.  Both types are designed for tens of thousands of extra starting cycles.  I could keep the A/C running for days on one tank of gas in my Prius.

 

The advantage would be very little additional circuitry needed and almost no change to the vehicle other than tapping +12, ground, and an accessory wire that you've tested goes low when the engine shuts off.  Probably just a standard accessory tap would work but you may have to go as far as tapping the power to the ignition system to be sure.  The core design would be the same for any vehicle.

 

You could take it a step further for safety and add a temperature probe and some additional circuitry that will sound the car horn if it gets too hot in the car.  That would add one more tap for the car horn.

 

Mountain Mist, there is a "Campers Fleamarket" section that is right underneath the "Camping with Pets" section in the directory here ... that is where everyone has been posting their Pods for sale at.

us.  They are never left alone.  They bark if someone enters our site, until we assess the situation, then

they are hushed if there is no problem.  They are walked numerous times per day, and always picked up

after.  (There's a sentence ending in two prepositions!)

Once, while walking them on a leash, we passed a site that had two Lhasa Apsos running free.  They

basically assaulted Jennifer and Baxter, and the only reason they weren't eaten is that the spaniels were

caught entirely by surprise.  (I call them "Laughing A$$holes", and they looked like a pair of angry bedroom

slippers....)

I'll be very happy to control my pack.  You have to control yours!

When we have left our Schnauzer/s behind, it was in a coach, with ac on and All the windows covered. Unless someone knocked on the door or another dog barked (the first dog barks and all the other dogs bark at THAT dog!) all was quiet on the home front.  We tested it often by driving off and coming right back , but not checking in. Just sat in the car for a while. Then opened up and gave her an "attagirl" and treat. Also, I am a friendly sort and spoke with a nearby camper, telling them we were leaving and if the dog barked ( and fitting in with the above reasons) for other reasons that I needed to know and would plan differently. We have a friend who had a Scottie that found out she could stand with her feet on the horn and when she barked the horn would blow. Since all of us were not gone long(and might have seemed long to everyone else), just leaving campground and going home to shower and pick up mail, the campers were rolling around laughing! Give an animal a tool!

 

 

This is Panzer.   She loves the Rpod and would rather sleep in it in the evening than sit around the campfire.    At this site we were boondocking by ourselves in a field.
