Truck down tonight?

Work the list in this order

1 — Mobile units

A truck that won't move needs a unit that rolls to it. Filter the list toMobile and call down it — and get the trip fee stated before any truck rolls.

2 — 24/7 claims

Shops claiming round-the-clock service are marked. A claim isn't a promise — but a 2am answer starts with the shops that say they answer.

3 — Tow vs road-call

Limping at 5mph under a derate? Drive it in — skip the tow. Dead pedal or crank-no-start? Ask for the tow price and the call-out trip fee on the phone before either truck rolls.

Before you call

Three questions that save the night

Ask these three on the call. A listing here means the shop’s public site was read and recorded — not that the shop was screened, ranked, or endorsed.

1 — Name the symptom

“Derated to 5 on the Gulf Freeway, DPF lamp flashing” gets a real answer. “Truck broke” gets a guess. Photograph the dash before you dial.

2 — The trip fee, up front

For a mobile unit, the first number is what it costs to roll — and whether any of it credits toward the repair if they do the work. Ask before the truck moves.

3 — Diagnose before parts

A shop that reads the fault before quoting sensors is a shop being straight with you. Ask if the diagnostic hour counts toward the repair — many here do it.

The full methodology →

By kind of work

Specialty guides

Mobile roadside

The truck won't come to a shop — units that roll to you, on the shoulder or in a yard.

DPF & emissions

Clogged filters, derates, sensors, forced regens.

Injectors & turbo

Fuel system and boost work: the two repairs that swing hardest on parts choice.

Engine rebuild

In-frame overhauls to complete rebuilds — Houston shops that open engines up.

Tires & roadside

Dual assemblies, roadside truck tire service, and heavy-duty towing.

Guide

DPF derate: the next 10 minutes

The truck just dropped to 5mph on the Gulf Freeway. What to do, in order, before you spend a dollar.
