Shopping for a Tundra Double Cab in Ontario usually starts with one question: which configuration actually pulls the trailer you own? The Double Cab lineup splits across cab, bed, and drivetrain choices, and the towing number changes with each one. Here is how the pieces fit together.
The Double Cab SR5 Long Bed, built on 4WD, is rated to tow up to 11,089 lbs (5,029 kg). That is the highest tow figure in the Double Cab range.
The Double Cab SR, in both Regular Bed and Long Bed form, tops out at 8,289 lbs (3,760 kg) whether you choose 2WD or 4WD. The gap between the two ratings is real, so confirming the trim and bed length matters before you shop for a trailer.
Every Double Cab grade shares the same 3.4 L twin-turbo V6, producing 358 hp and 406 lb-ft of torque through a 10-speed automatic transmission. The engine does not change between SR and SR5.
What changes is drivetrain availability and equipment. The SR is the only Double Cab grade offered with 2WD, in either bed length. 4WD is available on the SR and standard on the SR5 Long Bed. A TRD Off Road package builds on the SR 4WD Regular Bed, adding a locking rear differential, Crawl Control, Multi-Terrain Select, and TRD-tuned shocks. That package is about off-road control, not a higher tow rating.
The SR5 Long Bed steps up in daily comfort, too: heated front seats, an 8-way power driver and passenger seat, dual-zone climate control, and a leather-wrapped, heated steering wheel all come standard, none of which appear on the base SR.
The SR Regular Bed carries a 78-inch cargo box. The SR5 Long Bed stretches that to 97.2 inches (2,469 mm), a meaningful difference if you haul long lumber, ladders, or larger recreational gear alongside towing a trailer.
The longer box on the SR5 Long Bed pairs with the higher tow rating, so the trim that gives you more bed length is also the one that gives you the most pulling capacity. If your priority is trailer weight over cargo bed length, that pairing works in your favour. If you need maximum manoeuvrability for tight driveways or parking, the Regular Bed keeps the truck shorter at the cost of towing headroom.
A Tow Package with a heavy-duty tow hitch receiver, hitch plug, and ball mount is standard across every Double Cab configuration, including the base SR 2WD. A trailer ball is standard on most grades as well.
A trailer brake controller comes standard on the SR5 Long Bed. On the SR 4WD Regular Bed it is available as part of an optional package, and it is not offered on the 2WD grades at all.
Power extendable and folding towing mirrors are not standard on any Double Cab grade. They are available as an optional package on the SR Regular Bed 4WD, bundled with the TRD Off Road equipment. The SR5 Long Bed relies on standard power-adjustable heated mirrors instead.
A backup camera with Back Guide Monitor is standard across the entire Double Cab lineup, on the base SR and the SR5 Long Bed alike. That covers routine hitching and reversing tasks without an upgrade.
Blind Spot Monitoring with Rear Cross Traffic Alert and Intuitive Parking Assist with Auto Braking are available as an optional package on the SR 4WD Regular Bed. Neither is listed as available on the SR5 Long Bed configuration.
The CrewMax 1794 with Towing Mirrors is rated to tow up to 5,010 kg (11,045 lbs (5,010 kg)). That sits close to, but just under, the Double Cab SR5 Long Bed’s 11,089 lb (5,030 kg) rating. The two cabs land in the same towing range, so cab choice comes down to passenger space and bed length rather than a large gap in capability.

Payload trades slightly lower on the SR5 Long Bed even as the tow rating climbs, worth factoring in if you load the bed heavily on the same trips you tow.
If you tow occasionally, a light utility trailer or small boat, the SR Regular Bed’s 8,289 lb (3,760 kg) rating and standard hitch hardware cover the job without paying for equipment you rarely use.
If towing is a regular part of ownership, a larger travel trailer, a car hauler, or work equipment, the SR5 Long Bed’s 11,089 lb (5,030 kg) rating, standard trailer brake controller, and longer box give you more margin and less guesswork at the hitch.
The 2026 Tundra Double Cab spans a wide towing range, from 8,289 lbs (3,760 kg) on the SR to 11,089 lbs (5,030 kg) on the SR5 Long Bed, with hitch hardware, trailer brake controllers, and mirror options that shift by trim and bed length. Matching the right configuration to your trailer starts with knowing which of those boxes you actually need checked.
