Looking for a/c for truck

Now that our family has expanded it is getting easily cramped transfering everyone in the cab of our pickup truck.

I legitimately do not want to trade the truck in for a minivan or an SUV.

I am a truck girl through and through, however, I would legitimately prefer to find a way to cool the covered bed of our truck so that our sizable hound dog can ride back there. This would free up a lot of space in the cab. The only issue is that it might get tepid in the truck bed, but of course, I never would leave our dog in the motorcar unattended despite the fact that I would prefer to find some sort of a/c that works in the bed of the truck while he travels back there. I was looking at some of those portable a/cs that can be blocked into the cigarette lighter but they have easily mixed reviews. It seems they are more of a swamp cooler than an actual a/c and I don’t feel how much help they would really offer in cooling down the bed of our truck. I saw someone with a real window device A/C hooked up to the bed of their truck. I am not sure how they are supplying that much power to run the a/c though. I suspect the window A/C is only used when the truck is parked. They absolutely camp back there or something. I assume I am just trying to figure out if there are any legitimately a/cs that run off of the cigarette lighter that could keep a covered truck bed cool enough for our cat… So far, I have not found any.
