Portable Restroom Trucks That Keep Your Crew on Route

Amthor International has delivered more portable restroom service trucks than any other manufacturer in the United States. The Matador line — Runabout, Flat Vac, Slide-In, and Trailer — covers every route requirement from a high-volume multi-stop operation to a single-truck startup that needs maximum flexibility without a CDL. Every unit is custom-built in Gretna, Virginia, to your tank size, pump system, and chassis requirements.

The Matador Lineup

The Matador Lineup — Built for Every Route, Every Operation

No two portable restroom operations run the same route. A company servicing construction sites across a metro area has different clearance requirements than one running a rural event circuit. A startup building its first truck has different capacity needs than an established operator adding a fourth vehicle. The Matador line is designed to cover every scenario — with full customization on tank size, pump system, vacuum rating, compartment configuration, and chassis compatibility.

High-Capacity Route Truck

Matador Runabout

The flagship of the Matador line — a full-height, high-capacity portable restroom service truck for open-access routes where overhead clearance isn't a constraint. Built to your tank size, vacuum rating, and pump system, the Runabout carries the waste and freshwater capacity to run long production days between dump cycles. Every unit is built from customer-approved CAD drawings, with the wraparound troughs, rub rails, and hose protection that make a Matador last.

Amthor Matador Flat Vac truck

Low-Profile Route Truck

Matador Flat Vac

Built for operators whose routes include tight overhead clearances — parking structures, under bridges, low-clearance construction site entries, and dense urban neighborhoods. The Flat Vac delivers the same service capability as the Runabout in a lower-profile body that fits where full-height trucks cannot. More stops, fewer detours, less time lost to clearance issues.

Amthor Slide-In Vacuum Tank

Start Without a CDL

Slide-In Vacuum Tank

The Slide-In is the entry point for operators building their first route — or adding service capacity without adding a CDL driver to their payroll. The tank slides into and straps down to the bed of a pickup truck or flatbed, giving you a functional portable restroom service unit without the overhead of a full tanker truck. Handles portable toilet waste, greywater, and liquid waste from trailers and other sources.

Why Portable Restroom Operators Choose Amthor International

More portable toilet trucks have left Amthor's Gretna, Virginia facility than any other manufacturer in the United States. That is not a marketing claim — it is the result of fifty years of building specifically for the requirements of portable sanitation operators. The Matador line exists because Brian Amthor's team listened to what operators were losing time and money on — clearance issues, vacuum pump failures, tank damage from toilet handling — and engineered solutions for each one.

Configured for Your Route

Tank size, vacuum rating, pump system, compartment configuration, and chassis — every Matador is built to your specific route requirements and signed off on CAD drawings before fabrication begins. No catalog, no compromises.

Built for the Abuse of Daily Service

Wraparound troughs, TREX-board-protected rear bars, outside rub rails, and hose protector plates. Every protective feature on a Matador exists because operators told us what was getting damaged in the field.

Backed by Next-Day Parts

When a pump seal or vacuum component fails mid-season, next-day parts shipping from Gretna, Virginia, means your truck is back on the route the next morning. We support the trucks we build for the full life of the vehicle.

Frequently Asked Questions — Portable Restroom Trucks

What is the difference between the Matador Runabout and Flat Vac?

The primary difference is tank body height and the clearance profile of the vehicle. The Runabout is a full-height, high-capacity unit best suited for open-access routes where overhead clearance is not a constraint. The Flat Vac has a lower-profile body designed for routes that include parking structures, low bridges, or urban environments where a full-height truck would need to detour. Both are fully configurable for tank size, pump system, and chassis.

Do I need a CDL to operate a Slide-In Vacuum Tank?

CDL requirements depend on the gross vehicle weight rating of the pickup or flatbed on which the Slide-In is mounted. In many configurations, the combined weight falls below the CDL threshold — but Amthor recommends confirming the specific GVWR of your intended vehicle against your state's CDL requirements before purchase.

Can Amthor build a Matador unit on my existing chassis?

Yes. Customers can supply their own chassis for a seamless integration process. Amthor works directly with chassis manufacturers and can source any make or model if you prefer to have the chassis supplied as part of the order.
