Since that fan is designed to cool a car, I have no doubts it will cool this generator. My only concern is the exhaust pipe, and that the heat will affect the sound deadening material. I may get some exhaust wrap tomorrow to wrap the area that is inside the box.

It's on my list of things to get tomorrow. :wink:

The fuel pickups are already installed in the tank. Peterbilt was nice enough to install a supply and return line at the factory specifically for running an APU.

mine is water cooled and I use a point and shoot infrared thermometer to check the running temp.

I think I may invest in a thermometer to see what kind of running temps I'm getting.
Here's some pics of the vents:
Now on to the air conditioner. Please note that I will be having a louvered surround built for it to cover the exterior, which will be painted the same cream color as the truck.
The only issue I've run into with the AC is that the water drips down the side of the truck. I think the best solution for that is to have a small channel built to direct it away from the truck about an inch or so. I'm sure I'll always run into issues with it splashing on the truck, but I wash it on a regular basis, so I don't see that it will stain the side of the truck.
The AC unit sticks out about one inch on the top, and about 3/4" on the bottom. I've had several people look at the truck already, and most didn't even notice there was an air conditioner in the window.
The AC puts out 12,000 BTU, and I've had it running on and off for a couple of days already, and it keeps the sleeper at a nice temperature. It does not seem to have enough power to keep the cab cool though. As far as noise, it compares to a standard metal 12V fan, so it isn't too terrible. The body of the AC is over the bed about 6 inches, which I can live with.
