5 Minutes!!!!!! **** what a lucky man you are. With my sweetie, it's a case of if there is still hot water available (warm even) then I must not be clean. Doesn't mater if it's at home or on the road they only way I'm getting hot water is to get in first, or to wait the recovery period which on a 40 gallon tank at home can take a while. So if there is something I can do to give her a good supply of hot in the MH (and allow me to have some as well) then that's what I would like to do. Happy wife, happy life.
