No APU - A/C options??

I idle. It uses surprisingly little fuel.

 

I once saw a guy that had rigged up a piece of light duty flex hose (like clothing dryer vent hose) from the front vent door of the reefer to the driver side window. Each end of the hose had some sort of box (looked homemade) attached to it that fit the vent door and the window openings. I imagine something like this would work pretty good... Especially if you placed a small fan in the window box to draw air through the hose from the reefer.

 

How much is the fuel bonus??? It May pay better to forget the fuel bonus and keep your foot on the floor and get more miles, instead of puttering along going slow to conserve fuel?

Then you can idle to your hearts content.

 

if you do a portable stand alone ac system. go with a 2 hose unit.

 

I've seen this 'solution' before, too.

 

block of ice and a fan....seriously....idle the truck..if boss says you cant Id say goodbye

 

And of course, if the temp is mild outside, say between 50-70 F, just open a few vents.

 

I’ve seen 3 so far. Gasoline generator, with a 500 btu a/c unit in passenger window. I had a 850 btu single hose portable, running off 2000 watt Generator. All bought at Walmart, It worked good at night, but not so good above certain point, 85 daytime- no good. Like Truckdriver31 said 2 hose portable units are better. Single hose units a waste of time.

 

It's like a sauna outside this morning in San Antonio. Not in my truck though... up to 9 mpg by turning the key off every time the truck stops and keeping my foot out of it.

This runs off a 3500 watt gas generator—$5 a day.
