Good chance early 2017 I will be buying my first ever RV , Class A or C. I like cold weather. What should I look for if I want to use the RV during cold winter season ?
Heated floors. Seriously, the floors get cold and the cold penetrates thru your feet and legs and you feel cold. Whatever you buy I suggest an area rug or something that will add another layer for warmth on the floor.
The holding tanks should be heated, you may want to consider getting double pane windows, and the fresh water tank and water lines should be in a heated area. Many companies market 4 season packages that include these things plus additional insulation.
