Smarter Mobile Refueling for the Treasure Valley: Boss Fuel Trailers in Boise & Caldwell

At Riverside Trailers Caldwell, we understand that when your tractors, harvesters, or excavators run dry in the middle of a tight seasonal window, every minute spent driving back to a fuel station directly strips away your profitability. Moving high volumes of combustible fuel between job sites in Boise County or large agricultural blocks in Caldwell County traditionally came with massive regulatory hurdles. Boss Fuel Trailers completely solves this problem by merging heavy-duty structural steel craftsmanship with brilliant compliance engineering. Built with rugged 6-inch to 8-inch channel frames, premium Dexter torsion axles, and 3/16-inch thick smooth plate steel tanks, these mobile fueling stations handle the punishing vibration of local farm paths and high-speed highway hauls down I-84 with ease.

The Non-Hazmat Revolution: Multi-Tank Systems (MT-660 & MT-880)

The primary game-changer on our lot is the innovative line of Boss Multi-Tank Fuel Trailers, including the popular MT-440, MT-660, and MT-880 models. By leveraging strict Department of Transportation (DOT) exemptions, these rigs allow your crew members to haul massive bulk quantities of diesel fuel completely legally without needing a specialized Commercial Driver’s License (CDL), a hazardous materials (HAZMAT) endorsement, or vehicle placards. How does it work?

  • Individual 110-Gallon Isolations: Instead of using one massive bulk cell, Boss structures the trailer using a series of independent, heavy-duty 110-gallon smooth-plate rectangular tanks. Because each tank stays safely below the federal 119-gallon bulk transport threshold, the load is legally classified as non-bulk.
  • Integrated Manifold Logistics: Every tank is linked to a heavy-duty, commercial-grade bottom manifold system equipped with individual 1-inch manual shut-off valves. This allows you to legally transport the trailer fully loaded, and then open the manifold lines on-site to pump fuel from all tanks continuously using a single high-flow hose.

Dedicated High-Capacity & Farm Use Only Refueling (FT-550 & FT-990)

For large-scale agricultural enterprises, feedlots, and local growers who utilize private farm roads or manage dedicated local fuel storage exemptions, the Boss Farm Use Only single-tank series provides unmatched volume. Models like the massive FT-990 and the highly versatile FT-550 utilize single, high-capacity smooth-plate square tanks equipped with top-mounted fuel gauges, 2-inch dual fill ports, and 1-inch lowpoint drains. These platforms drastically minimize downtime during critical planting and harvesting seasons, ensuring your high-horsepower tractors and combines stay 100% fueled without constant trips back to the home base.

Skid-Mounted Systems & Comprehensive Mobile Lube Trailers

To support every level of off-grid fleet maintenance, Boss engineers heavy-duty specialty configurations designed to serve as a complete field service station:

  • Heavy-Duty Skid-Mounted Tanks (FT200SKID Series): Designed for local hotshotters, mechanics, and ranchers who prefer utility bed configurations. These compact, heavy-gauge steel 200-gallon skid assemblies can be easily forklifted directly into a heavy-duty pickup truck bed or onto an existing flatbed deck to deliver fast, localized on-site refueling.
  • Multi-Fluid Mobile Lube Platforms: The ultimate maintenance asset for heavy dirt contractors and agricultural operations. Advanced configurations can combine a 550-gallon diesel core with dedicated individual cells for hydraulic fluid, fresh engine oil, reclaimed oil, and an automated pneumatic greasing system—all routed to dedicated spring-retractable hose reels in an oversized rear cabinet workspace.

Premium Upgrades: DEF Integration, Solar Power, and Power Generators

Customizing your Boss Fuel trailer to act as a self-sustaining job site hub is effortless, thanks to an extensive array of high-utility options available on our lot:

  • Diesel Exhaust Fluid (DEF) Kits: Keep Tier-4 commercial engines compliant with integrated 75 or 90-gallon poly DEF tanks. These premium packages come equipped with dedicated 9 GPM electric pumps, specialized digital in-line flow meters, and heavy-duty 25-foot to 50-foot spring-retractable hose reels.
  • Enclosed Storage Cabinets & Toolboxes: Protect your pumping systems, digital meters, and tools from dust and theft. Choose from Large or Extra-Large front tongue enclosures featuring dual doors on each side, or a spacious 60-inch wide rear-enclosed walk-by tool cabinet.
  • High-Flow Pumps & Electric Start Gas Motors: Move fuel rapidly with upgraded 25 GPM 12V electric pumps or high-efficiency Kohler and Honda electric-start gas engines driving high-capacity mechanical pumps capable of breaking up to 30 to 35 GPM flow rates.
  • Off-Grid Solar Charging Modules: Eliminate dead battery delays. Adding a factory-installed 7-watt or 12-watt solar panel charger continuously maintains your 12V battery and pump charging systems under the open Idaho sun.
