Anyone heard of a Combo AC/DC Air conditioner?

Keep in mind that, unlike humans, dogs do not use evaporative cooling (we sweat) to keep cool. They pant through their tongue or find a cool spot to lay on. SO, humid air does not matter, just the temp of the air. You CAN use evaporative cooling like those that blow air out of an ice-filled cooler and the dogs will be happy.

You are talking major battery usage to run any AC (powered by A/C or DC doesnt matter), so it will be cheaper to run a generator than to do such damage to batteries. Anytime you deplete or use a battery it is damage. There are only so many "cycles" any battery can do and running an A/C unit will surly induce a deep discharge. Solar is of not much use unless you have a big roof covered completely with panels.
You will spend more on batteries due to short life than you will on gasoline.

I would look more into the personal cooling contraptions. The room does not need to be cooled, only the air blowing on the dogs. They will be happy sitting in that one cool spot all day long.

KINGTEC makes DC air conditioners.
Did not hear about combos

Sounds like you could run that off batteries for a decent amount of time as well.

I think the generator thing depends a little on where you are parking - if we are talking a mall parking lot then generator away. If you are thinking trailhead, picnic area, national park then running a generator for hours a time could be a bit inconsiderate.

Personal portable cooling fans, aka swamp coolers....
Are you familiar with swamp coolers and that they don really work in humid environments?

What is your fear of leaving the generator running unattended? Is it a built-in or a portable unit? All of the built-in’s I’m familiar with have adequate safety shut-downs as part of their design. Actually, all the portables do too, but you may be rightly concerned about theft.

If you have a built-in that’s in good running condition, it may make more sense to invest in a means of remote monitoring the temperature in your RV, and getting alerts sent to your phone if there is a problem.

We have had no problem leaving the cat in the TC on hot days with the two Fantastic Fans blowing one in one out and the TC cab over windows open also the smaller kitchen window. He actually seems to like it laying on the bed with his head in the breeze to sniff. 264 watts of solar panels easily manages the power requirement. If the cat wants AC, he can pay for it!

I have a Honda 2000 securely mounted on a torklift side kick rack on my front hitch (locking pins). I can run my polarcub 9200 AC for 6 hours from there. Keeps our dogs cool in the TC if we are out and about where we can't take them with us

coachman beyond class b offers an option of a 20,000 btu 12v ac. But i don't recall seeing the manufacture. 600 amp hr with the e package. maybe helpfull?

Chaisama,

Welcome to the forums.

For each battery count on about 1200 watt-hours. How many watts of solar panels do you have? How big is the inverter?

There are DC air conditioners but they may be 48 volts dc.

I think the unit you mentioned is called a swamp cooler. They work better in extremely dry climates.
