Best portable air conditioner for the truck?

If you're confident in your ability to do minor electrical and HVAC, it's a pretty simple job. It does help to have two people to feed the tubing so it doesn't kink. My first unit I mounted the indoor unit over the lower sleeper window on a sheet of plywood. It would get really cold at night since it blew right on the bed. The second unit I mounted it up where the top bunk used to be. There is a function on the remote called "follow me" that lets the remote act as the thermostat. I turn that on and mount the remote next to the bed, and it works perfectly.

 

Up to a point. I've never had it too hot that the AC couldn't keep it comfortable. The heat works great until you get close to freezing, then it starts to lose its effectiveness. I believe it has to defrost the outdoor unit more often, which causes it to fall behind during that process. It's not drastic like grab a jacket level cold, but I usually grab a long sleeve shirt if awake or a blanket for bed. Any colder than that and I use the bunk heater or idle.

I'd probably guess I idle when it's below 15F. Between 15-40F I will use the bunk heater. Above 40F I use the mini split.

 

Here is an option. Its a bit pricey at $3000. I like the permanent under bunk installation. The fan can mount to rear of cab or underneath. They will install for $1200. Or ship to you factory direct for $600. Pretty straight forward install. The price sucks but I really like this set up.

Dometic Truck AC Units

The wording says “like new”. I forgot to ask about that. Since it was coming from the factory I assumed it was new.

 

Man, Dino, you're early. All the AC threads don't usually start til May or so.

 

If you have a flat top you can get a Coleman roughneck and put it on the roof. They will freeze you out, and you can add a heat strip also. They are made for RV's so much more robust for on the road.
There is a thread on here someplace from a guy who installs on in a mid roof Western Star, and it worked great. If I didnt have a co do I'd be ALL over one of those.
With the unit on the roof, hot air rises so it works great for ac.

 

Pioneer also offers a 115v under bench rv style for 1199 bucks. That may be the best option. Mount it under the bunk and everything is inside and out of the weather.
