Bunk Heater Installation

Ok all you gurus. Need a little help here. I am going to install a couple of new bunk heaters in my sleepers in the next couple of weeks. Pretty simple to install, but in the instructions do not suggest where to run the intake or exhaust for the unit. Is the back of the cab fine to exhaust or where is the best place ?

 

Thanks swann, should be easy enough to run my lines like that. I do have one driver that is kind of irritating me lately. Was thinking maybe I could exhaust it in the bunk.

 

I bought a couple of Snuggers. The price was right, and so far they have worked very well. Tine will tell. I am right across the border from their main headquarters, so parts are fast and easy. Parts are readily available, and about half the cost of the Espar and Webasto heaters. I bought mine off Ebay if I remember correctly, and was a little over 500.00 per heater for complete package.
