Water tanks are a useful tool in your travel trailer setup. They can be used to hold drinking water, sink or shower water (sometimes called grey water), and wastewater (sometimes called black water). Depending on the model of your trailer, camper, or RV, there are different size dimensions to keep in mind in order to make sure that your travel trailer holding tank fits safely and securely in your trailer. Here at Vintage Trailer Supply, we stock fresh water, grey water, and black water tanks for Airstreams from 1970 - 1975 as well as other vintage trailer models. Along with our water tanks, we offer additional plumbing and water system management tools and accessories, including portable water tanks for removing waste water, hoses, valves, caps and more. No matter your vintage trailer model and no matter your size restrictions, shop Vintage Trailer Supply for your Airstream water tank needs.
