Editor's Pick: For long RV road trips when you want a hot shower anytime, the 12-gallon capacity is enough for the whole family to take turns. The tank is porcelain-lined steel with a replaceable anode rod, so it resists scale buildup and corrosion over time. The flue design slows down combustion so heat transfers more fully, heating water faster while saving gas. If you want to hook up to campground power or a generator, just add an electric heating element—it's flexible for off-grid parking.
