more inför for added heat duct in underbelly
More info for Daryles, BTW, when installing the duct as described in earlier post, I also redirected the factory duct to blow heated air more so on the black tank and the grey tank beneath the basement area. This along with the duct I previously installed keep the underbelly from freezing without having to winterize the water system. At 17 degrees, I checked the temps in the underbelly using an extended probe where the hydraulic lines from the leveling system passed into the underside. temperature in the belly area was 36 degrees. Of course this also depends on your source of heat. As said before I used an oil filled heater allowing the heat to rise into the fan, (I left the ceiling grill off of the fan box) as seen in the photo the fan box is right next to an extension ladder I store in the ceiling of the basement.
