LOFTANK Water Tank 30 Gallon Portable
- Capacity: 30 gallons.
- Material: 1000D PVC with reinforced seams; high-frequency welded bonding.
- Opening: 1.5-inch wide opening for quick filling; 3/4″ PVC spigot outlet.
- Temperature range: -35 to +80 Celsius.
Best for trailer owners needing a portable, weather‑resistant water source that can be folded for storage when not in use. Choose this if you want a compact solution that still holds a solid amount of water. Caution: the bladder is not designed for continuous high‑pressure use in stationary setups.
VEVOR 105.7 Gallon Water Storage Bladder

- Includes: faucet valve, 3/4″ connector, fittings, repair patches; PTFE tape for leak‑proof connections.
- Temperature tolerance: 5°F – 167°F.
Best for large utility trailers or remote setups requiring significant water on hand. Better for long trips or off‑grid camping where frequent refilling isn’t possible. Avoid using with high pressure pumps that exceed the leakage threshold of the welded seams if not properly sealed.
RecPro RV 45 Gallon Fresh Water Holding Tank
- Capacity: 45 gallons.
- Durability: Uniform wall thickness for reliability.
- Fit: Designed for RVs, trailers, and campers with space efficiency in mind.
Best for trailer owners who need a solid mid‑size tank with consistent construction. This option suits those prioritizing durability and a low profile. Limitation: exact fittings are not listed, so verify compatibility with your trailer’s plumbing before purchase.
Class A Customs T-4159 41 Gallon Tank
- Capacity: 41 gallons.
- Material: NSF approved; features a long tank length with versatile orientation.
- Dimensions: 71″ long, 10″ x 14.625″ cross‑section; fittings positioned at one end.
Best for buyers needing a long, low‑profile solution compatible with side mounting or end‑to‑end placement. Choose this if you require flexibility in tank orientation to fit irregular trailer spaces. Caution: length and mounting must be checked against trailer dimensions to avoid interference with other components.
A.A 30 Gallon RV Fresh/Gray Tank
- Capacity: 30 gallons.
- Material: BPA‑free polyethylene; vented, non‑pressurized.
- Inlet/Connections: 1.25″ fill inlet; 3/8″ NPT connections; seamless one‑piece construction.

RecPro Fresh and Gray Water Combo Pack
- Contents: 10‑gallon and 16‑gallon tanks; total 26 gallons.
- Made in the USA; BPA free polyethylene.
- Tested to OEM standards; suitable for off‑grid or concession use.
Best for buyers who need a versatile, modular setup with mixed water storage options. Use this if you want separate fresh and gray water tanks in a single package. Caution: total capacity is smaller than single large tanks, so plan refills accordingly.
Buying Guide
What capacity do I actually need?
Assess the number of horses, typical travel time, and daily water consumption to estimate total daily needs. For short trips, 30–45 gallons may suffice; for longer rides or multiple horses, larger bladders or tanks (60+ gallons) reduce refilling frequency.
What material is best for horse trailer use?
PVC and polyethylene are common. Ensure the material is durable, food‑safe (if potable water), and able to withstand temperature fluctuations. Look for reinforced seams, leak‑proof fittings, and corrosion‑resistant outlets.
How important are fittings and hoses?
Verify inlet/outlet sizes and included hardware. Some units come with adapters, valves, or PTFE tape for leak resistance. A preinstalled sealing ring on outlets helps reduce installation time and leakage risk.
Is payload weight a concern?
Water is heavy. A 100‑gallon tank weighs roughly 850 pounds when full. Plan for trailer hitch balance, axle load, and tongue weight to avoid handling issues while driving.
Are portable bladders a better option than rigid tanks?
Bladders (like the 105.7‑gallon bag) offer flexibility and lighter weight when empty, but require careful positioning to prevent punctures. Rigid tanks provide consistent mounting and easier securing in fixed spaces but are heavier when full.
What about temperature and outdoor conditions?
Consider environments where you’ll park or travel. Some products tolerate freezing and heat; ensure the chosen model can withstand your local climate and trailer setup without cracking or warping.
What maintenance is needed?
Regularly inspect for leaks, check seals and gaskets, and clean the interior to prevent algae growth. Keep spare fittings and patches for quick repairs on the road.
Quick comparison by use case
- Short trips with limited space: LOFTANK 30 Gallon or A.A 30 Gallon are compact and simple.
- Long trips or large herds: VEVOR 105.7 Gallon offers substantial capacity.

FAQs
- What size water tank is ideal for a single horse trailer? A: For occasional trips, 30–45 gallons often suffices; for longer journeys or multiple horses, larger tanks (50–100+ gallons) may be needed.
- Do these tanks require special installation? A: Most tanks use standard inlets/outlets; ensure compatibility with your trailer fittings and venting requirements.
- Is a bladder better than a rigid tank? A: Bladders are lighter when empty and flexible, while rigid tanks offer stable mounting and easier cleaning. Choice depends on space and load considerations.
- Can I use these tanks for gray water as well as potable water? A: Some tanks are designed for fresh water; always verify material safety and labeling before use with drinking water.
- What maintenance steps are essential? A: Clean interior periodically, inspect seams and outlets for leaks, replace worn gaskets, and store in a dry place when not in use.
- How do I prevent leaks at connections? A: Use PTFE tape on threaded connections, tighten fittings to recommended torque, and replace damaged seals promptly.
