Customer Review: The Camco product is better built, more complete, and more functional than any other poop tote out there…and it’s cheaper than them…go figure.I have had a unit from Thet… and, though well made, it was incredibly poorly designed and was missing a key component (the drain valve for the tote).

Complete Buying Guide for Best Water Tanks For Trailers
Essential Factors We Consider
When selecting the best water tanks for trailers, we focus on several key aspects. Capacity is crucial – are you going for a weekend getaway or an extended expedition? Material is another vital factor; we prioritize BPA-free, food-grade plastics for potable water tanks to ensure your water remains safe and clean. Durability is paramount; tanks need to withstand vibrations, temperature changes, and potential impacts during transit. Ease of installation, including the presence of pre-drilled fittings or options for customization, also plays a significant role. Finally, we consider the tank’s shape and dimensions to ensure it fits snugly and efficiently within the available space in your trailer. For those looking at tanks specifically for pop-up campers, checking out our best water tank for pop up camper guide can provide more tailored advice.
Budget Planning
Water tanks for trailers can range significantly in price, from budget-friendly options to more premium models. Generally, smaller tanks with fewer features will be at the lower end, while larger capacity tanks or those with specialized designs (like integrated pumps or filters) will cost more. Consider your budget alongside your needs. For instance, if you’re looking for a basic fresh water tank and don’t need elaborate features, you can find excellent options without breaking the bank. On the other hand, if you’re planning extensive off-grid adventures, investing in a larger, more robust tank might be more economical in the long run than frequent refills. Don’t forget to factor in the cost of necessary fittings, hoses, and potentially a battery operated water pump for camping if your trailer doesn’t have one.
Final Thoughts
Choosing the right water tank for your trailer is a decision that directly impacts your comfort and convenience on the road. By carefully considering capacity, material, durability, and installation requirements, you can find a tank that perfectly complements your travel style. Whether you opt for a compact 12-gallon tank or a more substantial 36-gallon unit, having a reliable water source ensures you can focus on enjoying your adventures. Remember to also consider complementary accessories like water containers with spigots for easy access if you opt for an external setup, as detailed in our best water container with spigot for camping guide.
Frequently Asked Questions
Q: How do I determine the right size water tank for my trailer?
A: Consider how long you typically travel between water fill-ups and how many people will be using the water. A general rule of thumb is about 5-10 gallons per person per day for basic needs. For shorter trips, a smaller tank might suffice, while longer or off-grid adventures benefit from larger capacities.
Q: What is the difference between a fresh water tank and a waste water tank for trailers?
A: Fresh water tanks store water intended for drinking, cooking, and bathing. They must be made of food-grade, BPA-free materials. Waste water tanks (black or gray water tanks) store used water and are typically made of similar durable plastics but are not intended for potable water use.
Q: Can I install a water tank myself?
A: Yes, many water tanks are designed for DIY installation. You’ll need basic tools and an understanding of plumbing. Ensure you have a secure mounting location and proper fittings. If you’re unsure, consulting a professional RV technician is always a good option.
Q: How do I maintain my RV water tank?
A: Regularly clean your tank with a specialized RV tank cleaner to prevent bacteria and odor buildup. Sanitize the tank periodically, especially after prolonged storage, using a bleach solution (followed by thorough rinsing). Inspect fittings and hoses for leaks.
Q: Is BPA-free plastic important for RV water tanks?
A: Absolutely. For fresh water tanks that store potable water for drinking and cooking, BPA-free, food-grade plastic is essential to ensure the water is safe for consumption and free from harmful chemicals that can leach into the water.
Finding the ideal water tank for your trailer is a key step towards enhancing your mobile living experience. By understanding your needs and exploring the options available, you can equip your trailer with a reliable water source that supports all your adventures. Happy travels!
