Anyone using a humidifier in their RV. I wake up plugged up and dry with all that stale dry air being moved around. A friend of mine said they used a humidifier in the 5th wheel and loved it..
Wal Mart has a small humidifier that you fill with water, it as a absorbent pad, and fan that draws air through that pad. This increases the humidity, and as a side benefit, it will cool the air a bit at the same time. Cost is only about $25.
