I am looking to replace my original chassis batteries in the next year or sooner if they go bad. My coach was sold new in October of 2002. they are Interstate maint. free, and have always had a battery maintainer hooked up to them.(maintainer has gone bad and replaced but batteries are still good) I just replaced the house batteries last fall. It seems to be pretty straight foward and will probably go to Costco again. Their batteries are made by Interstate but if any trouble you need to return to Costco.
