Medium duty towing covers vehicles from 10,001 to 26,000 lbs GVWR: box trucks, delivery vans, shuttle buses, large pickups, and most Class B and C RVs. In San Diego, a medium duty tow typically runs $175 to $350 for the hook-up plus $7 to $12 per loaded mile. It’s the class most commercial drivers actually need, and the one most towing pages skip. Quick Tow SD dispatches medium duty units 24 hours a day across all of San Diego County, so a dead box truck in Vista gets the same response as a sedan downtown.
What counts as medium duty towing in San Diego?
Medium duty towing means any vehicle between 10,001 and 26,000 lbs GVWR, gross vehicle weight rating. That’s the number on the door placard, not what the vehicle weighs loaded that day. California’s weight classes break down like this:
| Class | GVWR | Typical vehicles |
|---|---|---|
| Light duty | Up to 10,000 lbs | Passenger cars, SUVs, small pickups |
| Medium duty | 10,001–26,000 lbs | Box trucks, sprinter vans, shuttle buses, food trucks, Class B and C RVs |
| Heavy duty | 26,001 lbs and up | Semi-tractors, combination units, large motorhomes |
The class matters because it decides the truck. A standard light duty flatbed can’t legally or safely load a 16,000 lb box truck. The boom rating, deck capacity, and braking all have to match the weight. If a company sends the wrong truck, you wait twice: once for the wrong unit, again for the right one.
If your vehicle sits under 10,000 lbs, our guide to light duty towing in San Diego covers that class. Above 26,000 lbs, you’re into heavy duty towing territory, and the rules change again.
How much does a medium duty tow cost in San Diego?
A medium duty tow in San Diego typically costs $175 to $350 for the hook-up, plus $7 to $12 per loaded mile. That lands most in-county tows between $250 and $600 total. The exact number depends on weight, distance, and whether the vehicle rolls freely.
| Scenario | Typical range |
|---|---|
| Box truck, 5-mile local tow | $225–$400 |
| Sprinter van, 15 miles across the county | $300–$550 |
| Shuttle bus or Class C RV, 25 miles | $400–$700 |
| Winch-out or loading complication | Add $75–$250 |
For comparison, standard car towing runs $95 to $150 for the hook-up plus $4 to $7 per mile; the full breakdown is in our guide to auto towing rates in San Diego. Heavy duty work starts around $350 to $600 before mileage. Medium duty sits between the two because the equipment costs more to run than a light duty flatbed but doesn’t need a heavy wrecker’s crew or permits.
Ask for the hook-up fee and the per-mile rate before the truck rolls. A dispatcher who can’t quote both is a red flag; our post on choosing a tow company covers the rest of them.
Which truck does the job: flatbed or wheel-lift?
Most medium duty tows in San Diego use a heavy flatbed or a medium duty wrecker with an under-reach. Which one shows up depends on the vehicle. Box trucks and vans with a working parking brake and intact axles usually ride an under-reach, towed on their rear wheels. Anything with drivetrain damage, low clearance, or cargo-shift risk goes on a flatbed deck rated for the weight.
The tradeoffs mirror the light duty world, just with bigger numbers. Our comparison of flatbed vs wheel-lift towing explains when each method protects the vehicle and when it doesn’t. For RVs specifically, the answer depends on class and length; the RV towing service page breaks down where each RV class lands.
One honest note: a true 26,000 lb load at the top of the class sometimes gets dispatched as a heavy duty job anyway, because the safe margin matters more than the label. If your rig is close to the line, tell the dispatcher the GVWR and let them size the truck.
Who calls for medium duty towing?
Mostly working vehicles. Delivery fleets, contractors with flatbed pickups, caterers with food trucks, church and school shuttle buses, and RV owners make up most medium duty calls in San Diego County. When a work vehicle dies, the cost isn’t just the tow, it’s the missed route or job. That’s why commercial tow truck service response time matters more in this class than any other.
Quick Tow SD runs medium duty calls 24/7 countywide, including the North County commercial corridors. A breakdown on Vista’s business parks gets covered by the same dispatch as towing in Vista, and the I-15 corridor through Escondido is a nightly run. After-hours breakdowns route through emergency towing dispatch, so a 2 a.m. box truck call doesn’t wait for business hours.
If your vehicle is over the 26,000 lb line, a semi-tractor or loaded combination unit, start with our guide to semi truck towing in San Diego instead.
Call (858) 923-5787 with the vehicle type, GVWR, and location, and dispatch will size the truck and quote the hook-up plus per-mile rate before rolling.
Frequently asked questions
Is a box truck a medium duty tow?
Yes, almost always. A 12 to 26 foot box truck runs 12,000 to 26,000 lbs GVWR, which puts it squarely in the medium duty class. A standard car flatbed can’t take it. Tell the dispatcher the truck’s length and GVWR so the right unit rolls first.
Can a medium duty tow truck move an RV?
Yes, if the RV’s GVWR is 26,000 lbs or under. That covers Class B camper vans and most Class C motorhomes. Larger Class A coaches usually exceed the line and need heavy duty equipment. Check the door placard or owner’s manual for the GVWR before you call.
How fast can a medium duty truck arrive in San Diego?
Typical response is 30 to 60 minutes inside San Diego County, a bit longer than a light duty call because fewer medium duty units are on the road. Freeway breakdowns and blocked driveways get priority. Giving dispatch the exact GVWR and location up front is the fastest way to cut the wait.
Does insurance cover a medium duty tow?
Commercial auto policies usually include towing or roadside coverage for fleet vehicles, but limits are often written for light duty rates. A $450 box truck tow can exceed a $100 towing limit, leaving the difference out of pocket. Check the policy’s towing limit, not just whether coverage exists.
What’s the difference between medium duty and heavy duty towing?
The line is 26,000 lbs GVWR. Medium duty covers 10,001 to 26,000 lbs with heavy flatbeds and under-reach wreckers. Heavy duty covers everything above it with integrated wreckers and rotators, higher rates, and extra CHP equipment requirements. Our heavy duty towing guide covers that class in full.
