The 10-gallon porcelain-lined steel tank is built for durability, ensuring longevity that mimics residential water heaters. The use of a replaceable anode rod provides advanced corrosion protection, which is a significant benefit for extending the unit's lifespan and simplifying maintenance.

This water heater features a direct spark ignition (DSI) system and an optional Incoloy electric element, making it versatile for use with either gas or electric power, perfect for various campsite setups. The product dimensions (16.22" x 16.22" x 20.50") make it a compact option, fitting well in most RVs while delivering a substantial 12,000 BTU/h heating capacity.

The recovery rate is commendable, with 10.1 gallons per hour on gas only and 6.1 gallons per hour on electric, ensuring a steady supply of hot water. However, the maximum flow rate of 0.45 gallons per minute may be a limitation for those requiring higher water flow. The heater's energy efficiency, augmented by Suburban's exclusive flue tube design, ensures optimal heat transfer and faster heating times, which could help save on energy costs. The product is backed by a 2-year limited warranty and a 3-year tank limited warranty, providing peace of mind. Weighing 46 pounds, it may require careful handling during installation. This water heater is a good fit for RV owners who prioritize durability, energy efficiency, and reliable performance, while those needing higher water flow rates might need to consider other options.

The Suburban Advantage RV Tank Water Heater SW10DEL is designed with a 10-gallon porcelain-lined steel tank, which is beneficial for durability and longevity. The inclusion of an anode rod helps to reduce corrosion, extending the heater's life span. With a Direct Spark Ignition (DSI), it provides a convenient and efficient way to ignite the heater without needing a pilot light.

The heater boasts a BTU rating of 12,000, indicating a decent heating capacity, and a watt rating of 1400, which is standard for electric elements. Its dimensions (16-7/32" Height x 16-7/32" Width x 20-1/2" Depth) make it a compact solution suitable for most RV spaces.

This heater is ideal for RV owners looking for a reliable and durable water heating solution.

The Suburban Advantage SW6DE is a solid choice for RV owners needing a reliable 6-gallon gas water heater with added electric heating options. Its porcelain-lined steel tank and replaceable anode rod provide good durability and corrosion protection, which means it should last well even with regular use. The direct spark ignition is convenient and dependable, eliminating the need for pilot lights. With a BTU output of 12,000, this heater delivers a respectable recovery rate—up to 10 gallons per hour on gas only—allowing you to get hot water fairly quickly after use. The optional 1,440-watt electric element is handy if you have access to shore power or a generator, offering extra flexibility. Its compact size (about 13 by 13 inches and 19 inches tall) makes it suitable for most RV spaces without demanding much room.

The exclusive flue design improves energy efficiency by heating water more evenly and faster, which can save on fuel consumption. On the downside, the 6-gallon capacity might feel limited for larger families or those who like longer showers, so users with greater hot water needs might want a larger tank. Also, while the unit is efficient and well-built, the 2-year limited warranty is somewhat modest compared to some competitors. Installation and maintenance should be straightforward, especially with the anode rod doubling as a drain, but beginners might still want professional help for setup.

For those seeking a durable, moderately sized RV water heater with flexible power options and good heating performance, the Suburban SW6DE is a dependable pick.
