Nobody likes dealing with rusted water tanks or leaks and messes, but that's what happens in an RV. It's bound to occur with frequent wear and tear at some point, but it doesn't have to leave you rushing for replacements. Whether you're hanging at the campground or planning long road and camping trips, you want to ensure you'll have enough water for everyday use. That means showering, bathing, washing dishes, or doing spring cleaning. What you should be doing is investing in Factory RV's Water Tank Combo. This combo includes a 30-gallon and 42-gallon water tank, giving you peace of mind that you're looking at a long-term upgrade for your RV. These water tanks can manage fresh or gray water, allowing you to utilize them as you see fit. With ⅛" wall thickness, you can rest assured that our water tanks will be resistant to cracks, rust, and corrosion for long-lasting performance on the road. For ease of installation, both tanks come pre-fitted with a ⅞" outlet, ½" outlet, and 2" inlet length, making these tanks compatible with standard RV plumbing systems.
