Thank you for the excellent write up and options given...that's the info I was looking for. One of the locations I was thinking of installing was where my now removed washer/dryer combo was...so that was and is a dedicated 20 amp circuit...the other spot is just below my electric panel in the MH(on the floor, of course) and should not pose a tremendous hardship to pull wires to( I have an empty breaker already in the panel). I will take a look at those heating carpets....I had never heard of theses, so Thanks for that too.
