04Why operators come back

A truck is a
balance sheet decision.

We have been selling heavy iron to working fleets since 1978. In that time the only thing that has kept customers coming back is being straight with them about what a unit is and what it costs to run.

  • The file comes with the truck

    Every certified unit ships with its full 140-point inspection record, service history and any repair invoices. You see the work before you sign, not after.

  • Warranty in writing

    Certified units carry 12 months and 100,000 miles of powertrain cover. Used units state their term on the listing. Nothing is left to a handshake.

  • Uptime is the product

    Two branches, 42 bays and 12 mobile units. Average roadside response inside our coverage map is under ninety minutes, around the clock.

  • Priced against the market

    We publish the price. No lead-capture gates, no 'call for pricing', no negotiating against a number you were never shown.

05After the sale

The part most dealers stop caring about.

Parts counter, service bays and mobile units across the network. The truck is the start of the relationship, not the end of it.

07Operators, on record

Fleets that buy twice.

Three customers running very different work, asked the same question: why did you come back?

We replaced fourteen tractors in eighteen months and Rocket Truck Center handled every one of them. What sold us was the reconditioning file — they showed us the work before we signed, not after.

I bought my first truck here in 2011 as an owner-operator. I now run nine. They never once talked me into more truck than the lanes could pay for.

The Granite arrived with the body already on it. That is three weeks of upfit delay we did not eat, on a job that had a hard start date.
