Delivery vans and box trucks spend their day idling with liftgates, refrigeration units, and telematics drawing power — and they die in the loading dock at 6am. We jump-start medium-duty vehicles safely, test the battery and charging system, and tell you whether it'll happen again tomorrow.

What we handle

12V and 24V jump-start capability
Box trucks, cutaways and step vans
Sprinter, Transit and ProMaster fleets
Dual-battery and auxiliary-battery systems
Liftgate battery checks
Alternator and charging-system testing
Battery replacement where a battery has failed

12V and 24V, not just the car-sized version

We carry professional 12V/24V jump-start equipment, so a 24V starting circuit on a diesel box truck or a fleet unit is a normal call rather than a reason to send someone else. Heavier tractors and semi-trucks: we jump those too when the vehicle's electrical system is compatible with our equipment, and we confirm that on scene before connecting. See semi truck & heavy-duty jump start or heavy-duty roadside assistance.

A boost is the start, not the answer

A jump gets the truck moving; the test tells you why it died. We check resting voltage, cranking voltage, and charging output on scene. A van that needs a jump every Monday has a parasitic draw or a failing alternator, and we'd rather you fix that once than call us weekly — even though weekly would be good for us.

Before we arrive

Turn off the liftgate, the reefer unit if it runs off the chassis, and the cab accessories. Leave the hood latched but ready.

Where we go
