We have a 2010 Big Horn 5th wheel. We have a heated mattress pad. We think they are so much better than an electric blanket. With the electric blanket, it's so easy to get the blanket all twisted up during the night. But with the heated mattress pad, the pad stays in one place. Always get the pad with dual controls. Hubby hardly uses it at all. I use my side probably 90% of the time. I usually start off with the pad on #9, just to get it warmed up. Hate climbing into a cold bed. I give it about 15 minutes to get warm. Nothing better.
