We are full time in a 06 32' DRV. It is too small and a new DRV is not in the mix. How do these units fare in cold weather, down to 0? My DRV is cold in slides. How are these? Can you really tow these with a short bed truck? Any axle problems? 7,000lbs axles seem underrated. My DRV has 8,000. I will likely have more questions later. Thanks and God bless.
