Enjoying the RV life can be a fun experience, whether hanging out at the campground or planning road or camping trips. But the more time you spend in your RV, the more wear and tear your things go through. It's only a matter of time before you need to start shopping for repairs, replacements, or upgrades. Your water system is vital to your RV, so letting that degrade should be a top priority. Factory RV's Water Tank Combo will ensure you invest in a high-quality water tank for long-lasting use. Even better, this combo comes with a 21-gallon and 30-gallon water tank, giving you flexible storage options for potable water in RVs, trailers, and custom builds. Made of high-quality polyethylene, our water tanks will resist rust, corrosion, and impact, so you can rest assured that this is a product that will endure the conditions of mobile and off-grid use. Each tank features a 2" inlet with a ⅞" internal diameter and a ½" outlet, making it compatible with standard RV plumbing systems for simple and easy installation.
