We just took our newly purchased 181 out for a shakedown trip and now we're looking forward to 2 weeks with it in FL after the holidays. DH insists I can't use my hair drying in the trailer, even with most other electrical appliances turned off. But after much surfing the net and these forums I don't see anything that supports his position. I have noted some precautions, such as not using the dryer while other appliances like the microwave are operating. Would like to hear from some MPG veterans out there about the do's and don'ts, if's and maybes of hair dryer use while on shore power. My travel dryer is 1675 watts.
