After last week's 8 deg temps and 30 kt winds in ND, I pondered a way to get some heat back to my bird dogs. I put a 26" bicycle tire between the sliding windows, inflated to seal the gaps. I closed the windows on the topp
er, turned up the heat in the cab and drove to workout. Like I hoped, the Venturi effect sucked air from the cabin back to coach...er, the topper..and the temp rose significantly in the 10 min drive to the weights and torture devices. So, I know it works, but how well and in what temps, etc.? Does it cool well enough in summer? Stay tuned.
