> prices out a SEER 21 9k minisplit
$800 is a little low.for a quality unit. I was referring to the cost of power, or how much energy even the most efficient model will draw in a poorly insulated camper/trailer.

You thought I was referring to the price of the unit. No.

I think he should get a mini-freezer, make popsicles, and stick one up his ass. A lot of blood flows through that sphincter.

Like above anon says, running aircon or a heater will suck away all your power, requiring a system 3x the original size - for Aircon - and so much bigger than that again, for electric heat, that in the case of regular full-electric heat, you'll never fit it in a mobile application. Maybe a small electric heating pad.

One of the issues as I pointed out, is trailers etc are poorly insulated. It's more of a problem with heat than aircon, hypothetically, because basically what you are usually doing with aircon is dehumidifying, first. And trailers can be more airtight than they can have a good R value. But because your trailer or van etc must be parked in the sun for it's rooftop panels to work, typically the cabin is absorbing more heat, than if you simply parked in the shade and used a fan.

Small scale swamp coolers only work well in low humidity. That, therefore is highly dependent on where you are using and building your system. The amount of water needed, can cause issues, too.
