Searching for air conditioner for truck bed

Now that our family has expanded it is getting easily cramped conveying most people in the cab of my pickup truck.

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

I am a truck boy through & through… However, I would truly enjoy to find a way to cool the covered bed of my truck so that our giant hound animal can ride back there. This would free up a lot of space in the cab. The only issue is that it might getboilingin the truck bed, and of course, I never would leave my animal in the vehicle unattended but I would enjoy to find some sort of air conditioner that works in the bed of the truck while he travels back there. I was looking at some of those portable air conditioners that can be blocked into the cigarette lighter however they have easily mixed reviews. It seems they are more of a swamp cooler than an actual air conditioner & I don’t think how much help they would truly offer in cooling down the bed of my truck. I saw someone with a real window unit cooling system hooked up to the bed of their truck. I am not sure how they are supplying that much power to run the air conditioner though. I suspect the window cooling system is only used when the truck is parked. They absolutely camp back there or something. I guess I am just trying to figure out if there are any truly air conditioners that run off of the cigarette lighter that could keep a covered truck bed cool enough for my cat, then so far, I have not found any.
