What Rampmaster does

Rampmaster (legal name General Transervice, Inc.) is a US-based manufacturer of aircraft refueling vehicles, founded in 1968 and headquartered in Coatesville, Pennsylvania. The company designs and builds a full range of modular jet refueler trucks from 3,000 to 17,500 gallons (including the world's largest non-articulating 17,500-gallon refueler), hydrant vehicles, and the self-regenerating electric RampCart. Its customer base spans major US commercial airlines (American Airlines, Delta), cargo and logistics integrators (FedEx, UPS), aerospace and defense primes (Boeing, Lockheed Martin), global ground handlers (Swissport, Menzies Aviation, Allied Aviation), aviation fuel service companies (World Fuel Services, AVFuel), and Fixed Base Operators (Signature Aviation, Modern Aviation). Rampmaster has held 80%+ market share of US commercial airline refuelers for more than two decades, with equipment deployed at all major US city airports and internationally across the Middle East, Asia-Pacific, and Latin America.

The company's competitive position rests on two patented technology platforms: the Engine Management System (EMS), which varies truck engine RPM in response to fuel flow requirements to reduce diesel consumption by up to 78% during pumping (independently confirmed by West Virginia University CAFEE), cut EPA emissions by 63%, and reduce engine wear by 46%; and a modular power/pump/tank architecture that allows field-exchanged repairs and extends refueler lifecycle from 10 to 20 years. In 2024, Rampmaster delivered the first zero-emission all-electric jet refueler in the United States to Signature Aviation's Eagle County Regional Airport, integrating Battle Motors chassis, Borgwarner Cascadia Motion motors, and Mobileye ADAS into its proprietary Electric Management System. Modular exchange restoration runs at roughly two-thirds the cost of a new unit, lowering customer total cost of ownership.

Rampmaster operates a direct enterprise field-sales motion through dedicated sales representatives, generating revenue from one-time equipment sales, multi-year equipment leases with terms up to 11 years (the industry's longest, sourced through financial partners), and recurring parts, repairs, training, and Concierge Exchange services on the installed base. In January 2026, Rampmaster was acquired by middle-market private equity firm ATL Partners — the first investment from ATL Fund III — and combined with SkyMark Companies to form a leading global specialty vehicle equipment platform for aviation refueling and ground support equipment, with the combined entity generating over USD 300M in annual revenue; Rampmaster's management team, led by CEO Leighton Yohannan and owners Owen and Daniel Watkins, retained leadership and rolled meaningful equity stakes into the combined company.

Core offering

Rampmaster designs and manufactures modular aircraft refueling trucks (jet refuelers) ranging from 3,000 to 17,500 gallons in capacity, including the world's largest non-articulating 17,500-gallon refueler and the first zero-emission 5,000-gallon all-electric E-lectric refueler delivered in the U.S. The trucks integrate a patented Engine Management System (EMS) that reduces diesel fuel consumption by up to 78% and emissions by 63%, plus a modular power/pump/tank architecture enabling exchange-based overhaul. The portfolio also includes terminal hydrant vehicles and the self-regenerating electric RampCart hydrant cart, sold primarily to commercial airlines, FBOs, into-plane agents, and cargo operators.

Product overview

Rampmaster is a manufacturer of aircraft refueling solutions serving commercial and general aviation markets. The company offers a comprehensive portfolio of modular jet refueler trucks ranging from 3,000 to 17,500 gallons, including the groundbreaking 5k Gallon E-lectric (zero-emission electric model) and the world's largest non-articulating 17,500 gallon refueler. Products are built on two patented core technologies: the Engine Management System (EMS) for fuel efficiency (up to 78% diesel savings) and the modular design allowing power, pump, and tank module exchanges that extend vehicle lifespan from 10 to 20 years. The product line spans small FBO refuelers (3k, 5k), mid-capacity commuter models (5k RJ, 7k S/SL, 7k RJ), and heavy-duty commercial airport refuelers (10k LS, 10k WD, 15k, 17.5k). Additional offerings include hydrant vehicles for terminal operations and the electric RampCart for narrow-body hydrant systems. Rampmaster acquired by ATL Partners in January 2026 to form a specialty vehicle equipment platform alongside SkyMark.
