You do not have to vent out the roof you can go out the side wall. Just make sure there is not a header that you are going through. Just make sure you flash over the top of the vent. I see all the time they are put in with no flashing just relying on silicone.....![]()
In Mikes case that's going to be a very long run to the outside. Plus most you guys are in the Extreme North were it gets very cold for very long periods of time. To run these units in the south for a day or three when the temp outside is in the 30's or 40's and you want to bring up the temp to 60-65 it's not going to make your windows sweat. If this was the case the windows would of sweat w/ the kerosene heater that you run now. You don't need to set the temp controls on kill, besides as many thing that I forget in the truck you will let plenty of fresh air in. :rofl:
