Towing capacity

There is also a possible confusion with MTWR with GCWR and tossed that and posted half ton (less than 8K GVWR) that the OP might have.

Really posting for both the OP and lurkers out there that PM me asking because almost everyone uses marketing nomenclature...half ton, 3/4 ton, 1 ton and then the modifiers = HD, Heavy Duty, Super Duty, etc.

Tried to keep it simple for the OP & lurkers, but it got out of hand, so posting latest and greatest model lines and their MTWR's...which fit right into the OP's numbers

The Best Chevrolet Silverado and GMC Sierra Half-Ton For Towing

For the 2021 model year, the highest tow rating for a Chevy Silverado 1500 or GMC Sierra 1500 is found in an extended-cab four-wheel-drive model equipped with the company's 6.2L V-8 engine and its NFT towing package. This gets a maximum rating of 13,300 pounds.

Silverado and Sierra models equipped with the 4.3L V-6 top out at 7,900 pounds, while those with the 2.7L I-4 bump up to 9,600 pounds. Trucks with the 5.3L V-8 can tow up to 11,500 pounds. Surprisingly, the 3.0L Duramax diesel tops out at a maximum towing of 9,500 pounds.


The Best Ford F-150 Half-Ton For Towing

For 2021, Ford reclaimed the best-in-class title for half-ton towing its F-150 pickup. Ford also has the largest number of cab and engine configurations in the class, along with available axle ratios, as well. This makes determining the actual tow rating of any truck a lot more difficult. (GM alleviates this confusion with stickers in the door jamb.) Confusion factor aside, the 3.5L EcoBoost V-6-equipped Ford F-150 can tow a maximum of 14,000 pounds. And this can be achieved with both Super Cab and Super Crew configured trucks in two-wheel drive.

Ford 5.0L V-8-equipped F-150 can tow up to 13,000 pounds in all cab configurations, while the 2.7L EcoBoost V-6 is capable of up to 10,100 pounds for Super Cab and Super Crew four-wheel-drive models. Ford's 3.0L Power Stroke diesel V-6 is available only in four-wheel-drive Super Cab and Super Crew models and is rated at a maximum of 12,100 pounds in both. The company's base 3.3L V-6 is rated at a max of 8,200 pounds in all cab configurations, and the new 3.5L Power Boost hybrid-equipped trucks can drag up to 12,700 pounds.

There are more, but this gets the message across that the OP might have a half ton with 12,500 MTWR
