Hot Tubs for real

why on earth wouldn't you just plug the hot tub into the spare 20 amp outlet on the post. why combine them? and yes, my softtub holds 220 gallons and that would cause some concern if I dumped it all at the site. and unless you are staying in a seasonal site getting the water hot would be impossible. IIRC they said on my softub that the water is heated by cooling off the pump motor it raises the temperature a few degrees per hour.
I bought my soft tub during a RV show at dulles airport after I saw a smaller one sitting on the back "porch" of a monster class A.
