Hi fellow RVERS, Any thoughts on the hot stick add ons for the hot water htr in our 2002 34' class A, any good results?? worth the $100+ for unit,remote sw etc?? We have a 6 gallon suburban w/ DSI. Have also thought of adding a residential 10 gallon 120v in series with the existing suburban htr. Have the room in a extra open area next to the water bay area, and then this would give us 16 gallons of hot water. Thanks for the help..Craig.
