After doing extensive research and using various RV water tanks, I have come to the conclusion that a 40 gallon RV water tank is the perfect size for most RVers. In this buying guide, I will share my first-hand experience and provide you with all the necessary information to help you make an informed decision when purchasing a 40 gallon RV water tank.

1. Determine Your Water Needs

The first step in choosing the right RV water tank is to determine your water needs. This will depend on the number of people traveling with you, the duration of your trips, and your daily water usage. A 40 gallon RV water tank is suitable for a family of two to four people who are planning trips that last up to a week.

2. Consider The Type of Tank

When it comes to RV water tanks, there are two main types: plastic and aluminum. Plastic tanks are more affordable, lightweight, and easy to install. On the other hand, aluminum tanks are more durable and can withstand extreme weather conditions. Depending on your budget and camping style, choose the type that best suits your needs.

3. Check The Quality

The quality of an RV water tank is crucial as it directly affects its durability and performance. Make sure to read reviews from other users or ask for recommendations from fellow RVers before making a purchase. Look for tanks made from food-grade materials that are BPA-free and safe for storing drinking water.

4. Check The Fittings And Accessories

An efficient water system requires proper fittings and accessories that allow for easy filling and draining of the tank. Make sure to check if the tank comes with all necessary fittings such as inlet/outlet ports, drain valves, vent caps, etc. Some tanks also come with additional features such as built-in gauges or sensors that indicate the level of water in the tank.

5. Consider The Weight And Size

A 40 gallon RV water tank can be quite heavy when filled with water, so it’s essential to consider its weight and size before purchasing one. Measure the space available in your RV where you plan to install the tank and make sure it fits comfortably without taking up too much space.

6.Make Sure It’s Easy To Clean And Maintain

Cleanliness is crucial when it comes to storing drinking water in an RV tank. Look for tanks that are easy to clean and maintain by having wide openings or removable caps for thorough cleaning.

7.Compare Prices And Warranty

Last but not least, compare prices from different brands while keeping in mind their quality and features offered. Also, make sure to check if there is any warranty provided by the manufacturer in case of any defects or malfunctions.
