Marc, if you leave the battery switch on to keep the batteries charged then be sure to check the water level in the batteries maybe once a month. Depending on the converter your coach has, it could boil the water out after a while. Our coach does that, but then it's a 2002. Yours may have the two or three stage charger that won't have that problem.
