🚒 That's a wrap on pump testing season! 🍂

We closed out the 2026 season today pump testing the Swansea, MA Fire Department apparatus, and honestly, we couldn't have asked for better October weather to do it in.

The trucks performed great across the board. Mark ran the show on our Draft Commander and, as usual, made it look way too easy. We're starting to think he just stands there and the pumps test themselves.

A big thank you to Chief Hajder and the Swansea Fire Dept team for being such great partners and choosing On Scene LLC. Having the next truck staged and ready every time kept the day running smooth from start to finish. That kind of teamwork makes a long day fly by.

Thanks to all our departments for another great season. See you next year!

We service Medix in CT, RI and MA...simple design, quality and reliability!

⚡Simple. Reliable. Easy to maintain.

Time and time again, customers tell us one of the things they appreciate most about a Medix ambulance is how easy it is to service, and our electrical system is a big reason why.

Electrical and environmental issues are among the leading causes of ambulance downtime. That's why we engineer our electrical systems to be straightforward, dependable, and easy to troubleshoot. Combined with responsive technical support from our service team, departments spend less time diagnosing problems and more time focused on serving their communities.

WHO THIS TRUCK IS FOR 🚒

We will be the first to say 250 gallons is about 90 seconds of water. So this isn't your engine replacement.

It's the apparatus that gets there first, in spaces your engine shouldn't be on, and puts water on it while everything else is still turning out.

Spencer Initial Attack #1740 is available now.

🛻 2024 Ford F-550 Crew Cab 4x4 · 6.7L diesel · 19,500 GVWR
💧 Hale DSD 1500 GPM · 250 gal · 10 gal Class A foam
📱 SAM pump control, screens both sides
🎯 Two SAM Smart Nozzles
🧱 Spencer Solid-Poly body — no rust, ever
🚿 Two 1¾" crosslays · 2½" front bumper line · 6" steamers both sides
🪜 12' ladder, pike poles, hard suction, 3 SCBA tubes

Here's why the small tank works. The Hale SAM smart nozzle gives the firefighter a tank gauge in their hand that displays green, yellow, red, and it flashes when you're about to be out. Meanwhile SAM handles the transition to hydrant or draft without anyone wrestling valves, auto-primes for draft, and refills the tank once you're on a source.

Small tank, fast source. That's the whole design.

That smart nozzle also holds your calibrated pressure up five floors, detects a kink and bumps pressure to clear it, and if it loses signal the line just works like a normal nozzle.

Who should be looking at this:
✅ Camp roads, dirt roads, long driveways, tight downtowns
✅ Anyone tired of putting engine miles on car fires and alarms
✅ No-hydrant departments running shuttle to feed a pump
✅ Replacing a tired mini-pumper, squad, or brush truck
✅ Departments where a custom engine won't clear town meeting

Lifetime body and tank warranty. Ten years on the stainless plumbing. Poly body means New England road salt is not your problem.
