RecPro 21 & 30 Gallon Combo Pack
The 21-gallon and 30-gallon twin-pack is designed for mixed-use on concession trailers or food trucks requiring a reliable fresh or gray water supply. Best for mid-sized operations that need a single purchase to cover both water roles. The combination’s high-capacity design helps reduce frequent emptying during busy service periods. Construction emphasizes a seamless, one-piece molded build with 1/8″ walls to minimize leaks and resist road wear.
Who it’s best for: food trucks with two separate water demands and a need for durable, US-made tanks. Why selected: high durability and a simple two-tank setup streamline installation. Caution: ensure compatible fittings with your existing plumbing to avoid retrofit work.
RecPro 16 & 21 Gallon Combo
This two-tank package provides flexible storage for smaller setups where space is at a premium. The heavier-duty polyethylene construction is naturally rust- and corrosion-resistant, making it suitable for mobile environments. Manufactured in the USA, it emphasizes consistent quality and reliable performance in demanding applications.
Who it’s best for: compact food trucks, pop-up trailers, or vans needing two moderate tanks without excess footprint. Why selected: compact size with dual-use capability. Caution: capacity may be limited for high-volume service days.
RecPro 30 & 42 Gallon Combo
Designed for larger mobile kitchens, this dual-tank setup delivers substantial total capacity for extended service periods. The package is ready for installation with standard inlet and outlet fittings compatible with common RV plumbing. American-made quality reinforces durability in transit and outdoor environments.
Who it’s best for: larger food trucks or concession teams with multiple prep areas. Why selected: high total capacity and reliable build. Caution: ensure your vehicle has space to accommodate taller tank configurations during installation.
Ameri-Kart 36 Gallon Fresh Water Tank
This tank focuses on potable water storage, suitable for drinking, cooking, cleaning, and showering in mobile setups. Built from BPA-free materials, it aims to meet safety considerations for food service environments. Multiple inlet options improve installation flexibility in kitchen layouts and vehicle structures.
Who it’s best for: operations needing a single, large potable water reservoir. Why selected: potable-water suitability and USA-made construction. Caution: verify that the tank’s fittings align with your vehicle’s plumbing layout to avoid custom adapters.
Class A Customs 31 Gallon Black Water Tank
This tank is designed for waste/gray water storage with a 3″ outlet and standard fittings guidance. It is explicitly marked not for fresh water use, making it a targeted choice for waste management in RV environments. Installation requires user-driven inlet and vent placement and may require additional hardware.
Who it’s best for: operators who need a dedicated waste water solution with a clear use-case. Why selected: tailored to waste disposal with practical outlet sizing. Caution: plan inlet and vent placement carefully, as hardware is not included and misplacement can complicate setup.
Buying Guide
What size best fits a food truck? Consider your daily water use, number of prep stations, and how often you will empty tanks. Dual-tank packs are convenient for separating fresh and gray water, while larger single tanks suit high-volume operations with limited installation space.
What materials matter?
Look for BPA-free plastics and seamless, rotational-molded construction. These features reduce the risk of leaks and improve durability on the road. Stainless components are less common in tanks, so focus on tank integrity and wall thickness as durability indicators.
What installation considerations should you review?
Check inlet and outlet sizes (commonly ¾” to 1½” NPT or similar), the availability of pre-fitted fittings, and compatibility with your existing plumbing. Consider the vehicle’s layout, weight distribution when full, and the need for venting to prevent airlock issues.
Are dual-tank configurations advantageous?
Yes when you want a dedicated supply for fresh water and a separate container for gray water. They’re especially useful for concession setups that require continuous operation during long shifts and for simplifying cleanup and sanitation routines.
What about portability and maintenance?
Portable tanks with no-flat wheels and sturdy handles are easier to move between dump sites. Regular inspection for cracks, fittings, and seals helps prevent leaks. Choose tanks designed for off-road environments if your service area includes uneven ground.
FAQ
- What is a good total capacity for a mid-sized food truck? Answer: A dual-pack around 37–60 gallons combined often covers typical daily use, with room to spare during peak service days.
- Do these tanks connect to standard RV plumbing? Answer: Most listed tanks use common inlet and outlet fittings compatible with RV plumbing systems, but verify exact sizes before purchase.
- Is it better to buy two smaller tanks or one larger tank? Answer: It depends on space and service style. Two tanks offer separate lines for clean and gray water; one large tank reduces fittings and potential leak points.
