Frequently Asked Questions
What fuel trailers do you carry?
We carry Boss 990 fuel trailers in three packages: a standard diesel fuel trailer, a “Better” package with a 90-gallon DEF tank, and a “Best” package that adds an enclosed tool cabinet and hydraulic jack. See Boss trailers →
What’s the difference between the standard, Better, and Best fuel trailers?
All three carry 990 gallons in a baffled tank with a 30 GPM gas-engine pump, 50′ hose reel, and tandem 7K axles. The Better package adds a 90-gallon DEF tank with its own 50′ reel, a lighted front storage compartment, and aluminum wheels. The Best package adds a lighted rear tool cabinet and a 12K hydraulic tongue jack.
Why buy a fuel trailer with DEF?
Most Tier 4 diesel tractors, loaders, and trucks need diesel exhaust fluid as well as fuel. A DEF trailer lets you top off both in one trip, so your equipment stays working in the field instead of heading back to the shop.
Who uses fuel trailers?
Farmers and ranchers fueling tractors and combines in the field, contractors and road crews keeping equipment running on job sites, and anyone who wants to bring fuel to the equipment instead of hauling equipment to the fuel.
Do you offer financing or rent-to-own on fuel trailers?
Yes. We offer trailer financing, and rent-to-own is available on select trailers. Apply for financing →
Can you special-order a fuel trailer?
Yes. If the package, pump, or DEF setup you need isn’t in stock, we can special-order Boss fuel trailers with the options you need. Contact us to get started →
