From refined fuel and propane to vacuum and portable sanitation — Amthor builds the tank truck your operation actually needs, to specifications you approve before we cut a single piece of metal.
01
We don't cut corners; we over-engineer. Amthor tanks are built exclusively from premium-grade aluminum, stainless steel, and carbon steel. Our rigs are built to withstand the toughest hauls. To ensure absolute precision, every single material selection is fully documented and approved by you before fabrication begins. No shortcuts. No substitutions. Period.
02
Every Amthor tank is fabricated to customer-approved CAD blueprints. Your compartment layout, chassis fit, mounting configuration, and equipment placement are engineered around your operation. You review and sign off on the drawings before we build.
03
Order a part and it ships the next day. Need service guidance? We pick up. Our team supports maintenance, warranty claims, and repairs for the life of your tank — not just until the check clears.
Our Heritage
Amthor International was founded in 1992 in the rural heart of Virginia — and we have been building custom tanker trucks right here, in the shadow of the Blue Ridge Mountains, ever since. What started as a family operation has grown into America's largest tanker truck manufacturer, with a brand-new 33,000 sq ft second facility in Gretna, Virginia.
Four generations of Amthor craftsmanship means we build like it is going on one of our own trucks — because our family name is on every weld, every bracket, and every bead. We do not outsource fabrication. We do not cut corners on materials.
