MM01What counts as medium duty

The trucks in the middle of the scale

Federal weight classes sort trucks by gross vehicle weight rating (GVWR), the most a truck is built to weigh fully loaded. Classes 4, 5 and 6 run from 14,001 to 26,000 pounds. The U.S. Department of Energy chart also counts Class 3 (10,001 to 14,000 pounds) as medium duty, so a truck near that line can go either way.

Cars, SUVs and pickups belong on our light-duty towing page. Anything rated over 26,000 pounds goes to heavy-duty towing.

  • MD-01

    Box and delivery trucks

    Straight trucks with a cargo box, from moving rentals to route delivery trucks. Breakdowns on a grade, dead batteries in the cold and slide-offs on snowy hills are the usual calls.

    Tell dispatchWhether the box is loaded, and with what.

  • MD-02

    Buses and shuttles

    School buses, church buses and the cutaway shuttles hotels and airports run. Long overhangs and low steps change how a bus is lifted.

    Tell dispatchWhether passengers are still on board, and how many seats it has.

  • MD-03

    Work and utility trucks

    Bucket trucks, service-body trucks, landscaping and plumbing trucks, small dump trucks and stake beds. When one is down, a crew is waiting.

    Tell dispatchAny boom, bed or gear that has to be stowed first.

  • MD-04

    Motorhomes and RVs

    Many Class C and gas Class A motorhomes ride on chassis rated in this range. The label on the driver's door tells you for sure.

    Tell dispatchThe length, and whether a car is hitched behind it.

MM02Door label reader

Read your door label, find your class

Every truck and bus carries a certification label on the driver's door edge or door pillar, and it lists the GVWR in pounds. Enter that number to see the weight class, the right towing page, and whether Colorado's commercial chain law and the federal CDL line apply.

− +

Type the number or step it by 500 pounds. Use GVWR, not the empty weight.

MM03How the work is done

How a medium-duty tow runs

A box truck or bus is longer and heavier than a pickup, and it is built differently underneath. Hooking it like a car is how transmissions and bumpers get damaged. This is the order the job runs in.

  1. The call

    Dispatch takes the vehicle type and GVWR, where it is stopped and which way it faces, whether it is loaded, and where it needs to go.

  2. Match the truck

    Weight, length and how the vehicle sits decide whether it goes on a wrecker or rides on a flatbed.

  3. Recover it first

    A truck in a ditch, a snowbank or soft ground is winched back onto solid footing before any tow starts.

  4. Prep for the road

    Air brakes, if the truck has them, are released or caged. If drive wheels will roll, the driveline is disconnected, as transmission makers such as Allison require for any tow.

  5. Tow and drop

    The vehicle goes to the shop, dealer, yard or home you choose, at a pace that suits the grade and the weather.

MP 259I-70 Morrison

Class 5 and 6 trucks used for business count as commercial vehicles under Colorado's chain law, and so do vehicles carrying 16 or more passengers. West of milepost 259 at Morrison, they must carry chains from September 1 to May 31. If the truck is losing the grade, pull off where it is safe and call before it slides.

MM04Cost and accounts

What decides the price of a medium-duty tow

Two box trucks with the same rating can be very different jobs. One is upright on a wide shoulder near the shop. The other is loaded, off the pavement and an hour up a canyon road. We do not post flat prices for that reason. Give dispatch the details that go into the quote and they will quote the job on the phone.

Businesses that run vans, trucks and buses lose money every hour a vehicle sits. D&J handles commercial vehicle towing and fleet support, so one call covers the delivery van, the bucket truck and the shuttle bus. We accept cash, Mastercard and Visa.

Our crew includes WreckMaster and I-TECC certified professionals, and D&J has been a family-owned towing company in Evergreen since 1984, working I-70, US 285, CO 74 and CO 119 in Colorado and the I-25 corridor in southeastern Wyoming.
