1. Transfer Flow 50 Gallon Rectangular Tank: Best Overall
In our evaluation, the Transfer Flow 50 gallon rectangular tank stands out for its strong construction and thoughtful design for short beds. The 12 gauge steel and powder coating offer durability that many competitors lack. Owners report the offset fill neck is a standout for trucks with toolboxes or fifth-wheel hitches, making it among the most flexible options.
However, the tank’s weight when full can be a drawback for solo installation, and some users noted the pump is somewhat noisy. This tank is best for those who prioritize longevity and a perfect fit over ultra-light weight. Skip it if you need a tank under 40 gallons for easier handling.
- Fits short beds with 5.5 to 6.5 ft length using optional offset fill neck
- 12 gauge steel with powder coat finish resists rust and dents
- Includes 12V pump, 12 ft hose, and automatic shut-off nozzle
Pros: Excellent build quality and fit for short beds; Automatic shut-off nozzle prevents overfills
Cons: Heavy when full, may require two people to install
2. RDS Manufacturing 40 Gallon Aluminum Tank: Best Lightweight Option
Based on owner feedback and spec sheets, the RDS 40 gallon aluminum tank is a top choice for short bed truck owners who need to save weight. The aluminum body is corrosion-resistant and the low profile allows it to sit under most tonneau covers without interference. We compared its dimensions and found it fits well in 5.5 ft beds with room to spare.
The main trade-off is durability: aluminum is softer than steel and can dent if cargo shifts. Also, the manual nozzle requires attention during fueling to avoid spills. This tank is ideal for light-duty use or if you frequently remove the tank. Skip it if you need a tank that can withstand heavy abuse.
- Aluminum construction is 40% lighter than steel tanks
- Low profile design fits under tonneau covers
- Includes 12V pump, 10 ft hose, and manual nozzle
Pros: Lightweight makes installation and removal easy; Aluminum won't rust, ideal for humid climates
Cons: Aluminum dents more easily than steel; Manual nozzle lacks automatic shut-off
3. Northern Tool + Equipment 50 Gallon Steel Tank: Best Value for Capacity
Our research shows the Northern Tool 50 gallon tank delivers excellent value for those who need maximum capacity. The 14 gauge steel is slightly thinner than premium tanks but still solid for typical use. Owner reviews highlight that it fits short beds well, though the fill neck position might conflict with a fifth-wheel hitch or toolbox.
The lack of an automatic shut-off nozzle is a notable drawback, and some users reported the pump is slow. This tank is best for budget-conscious buyers who can work around its limitations. Skip it if you want a tank with a smooth fit and modern features.
- Generous 50 gallon capacity at a competitive price point
- 14 gauge steel with black powder coat finish
- Includes 12V pump, 12 ft hose, and manual nozzle
Pros: High capacity for the price; Sturdy steel construction
Cons: No automatic shut-off nozzle; Fill neck location may interfere with some bed accessories
4. Better Built 35 Gallon Square Tank: Best Compact Fit
For short bed trucks with limited space, the Better Built 35 gallon square tank is a researched choice. Its dimensions allow it to sit forward in the bed, leaving room for tools or a cooler. We compared owner feedback and found it praised for its straightforward installation and compact profile.
However, the 16 gauge steel is more prone to dents, and the 35 gallon capacity may require more frequent refills for high-volume users. This tank is ideal for occasional use or those who prioritize space savings. Skip it if you need a heavy-duty tank for daily commercial fueling.
- Compact size fits easily in short beds with minimal overhang
- 16 gauge steel with red powder coat finish
- 12V pump with 10 ft hose and manual nozzle
Pros: Small footprint leaves room for other cargo; Easy to install and remove
Cons: Lower capacity may not suit heavy users; Thinner steel than premium options
5. Dee Zee 30 Gallon Low Profile Tank: Best Low Profile
Based on our evaluation of low-profile designs, the Dee Zee 30 gallon tank excels at staying out of sight. At only 12 inches tall, it’s one of the few tanks that can sit under a folding tonneau cover without lifting it. Owner feedback confirms it fits short beds well, especially when bed space is at a premium.
The trade-off is capacity: 30 gallons is on the low side for frequent users. The 8 ft hose is also shorter than average, which can be inconvenient when fueling trailers. This tank is best for truck owners who need a discreet, out-of-the-way solution. Skip it if you need to fuel multiple vehicles or large equipment.
- Ultra-low profile (12 inches tall) fits under most bed covers
- 14 gauge steel with black powder coat
- 12V pump with 8 ft hose and manual nozzle
Pros: Very low height allows tonneau cover use; Good build quality for the size
Cons: Small capacity (30 gallons); Short hose may limit reach
6. Westward 40 Gallon Skid Tank: Best for Durability
The Westward 40 gallon skid tank is built like a tank, literally. Our research into its construction reveals 12 gauge steel and a reinforced skid that protects the bottom from impacts. Owner reviews from contractors praise its longevity even in harsh environments. It fits short beds but the skid adds height, so measure carefully.
The downsides are weight and lack of modern features. At over 100 lbs empty, installation is a two-person job. The manual nozzle and basic pump feel dated. This tank is best for heavy-duty users who prioritize durability over convenience. Skip it if you need a lightweight or feature-rich tank.
- Heavy-duty 12 gauge steel with reinforced skid base
- Includes 12V pump, 12 ft hose, and manual nozzle
- Large fill opening with locking cap
Pros: Very durable, can withstand rough job site conditions; Reinforced base prevents damage
Cons: Heavy and bulky, difficult to install alone; No automatic shut-off, pump is basic
7. TrailFX 30 Gallon Aluminum Tank: Best for Off-Road
TrailFX’s 30 gallon aluminum tank targets off-road enthusiasts who need a lightweight, compact fuel solution. We evaluated its dimensions and found it fits short beds without protruding, and the aluminum construction resists rust from mud and water. Owner feedback highlights its ease of installation and low profile.
However, the thin aluminum is vulnerable to punctures from sharp rocks, and the 30 gallon capacity may not be enough for long expeditions. The manual nozzle and short hose also limit convenience. This tank is best for weekend adventurers who want a lightweight option. Skip it if you need a rugged tank for extreme conditions or high-volume fueling.
- Compact aluminum tank designed for off-road use
- Includes mounting brackets for secure fit
- 12V pump with 8 ft hose and manual nozzle
Pros: Lightweight and corrosion-resistant; Compact size leaves room for gear
Cons: Small capacity limits range; Thin aluminum can dent from rocks or debris
Frequently Asked Questions
Will a transfer tank fit in a 5.5 ft short bed?
Yes, many transfer tanks are designed for short beds. Look for tanks with overall length under 50 inches and consider offset fill necks to avoid interference with the wheel wells or tailgate. We recommend measuring your bed’s usable length and width before purchasing.
Do I need a special pump for diesel or gasoline?
Most transfer tanks come with a 12V pump suitable for diesel. For gasoline, ensure the pump is rated for flammable liquids and the tank is properly grounded. Always check the manufacturer’s specifications for fuel compatibility.
How do I secure a transfer tank in a short bed?
Use the tank’s built-in mounting brackets or add tie-down straps to anchor it to the bed’s cargo tie-downs. Some tanks have skid bases that can be bolted directly to the bed. Proper securing is critical for safety during sudden stops.
Can I use a transfer tank with a tonneau cover?
Yes, low-profile or compact tanks (under 15 inches tall) can fit under most folding or retractable tonneau covers. Check the tank height and cover clearance. Aluminum tanks are often preferred for their lighter weight and lower profile.
Are transfer tanks legal for on-road use?
In most states, transfer tanks are legal for on-road use as long as they’re properly secured and not leaking. Some states require a permit for tanks over 119 gallons. Always check local regulations regarding fuel transport and tank labeling.
