2019–2024 Dodge Durango: how do I know if it can tow 6,200, 7,400, or 8,700 lb?

Answered from the manual for the 2021 Dodge Durango.

Yes—on a 2021 Durango, the rating is not determined by engine alone. Match the specific vehicle’s engine, RWD/AWD configuration, cooling/tow equipment, and whether it is an R/T Tow N Go model to the factory towing table. The VIN/window sticker or a dealer VIN build sheet is the practical way to confirm the original configuration.

• 3.6L V6, RWD or AWD, Light Duty Cooling: 3,500 lb maximum trailer weight; 350 lb maximum tongue weight.
• 3.6L V6, RWD or AWD: 6,200 lb maximum trailer weight; 620 lb maximum tongue weight.
• 5.7L V8, RWD: 7,400 lb maximum trailer weight; 740 lb maximum tongue weight.
• 5.7L V8, AWD: 7,200 lb maximum trailer weight; 720 lb maximum tongue weight.
• 5.7L V8 AWD R/T Tow N Go: 8,700 lb maximum trailer weight; 870 lb maximum tongue weight.

So a listing’s “8,700 lb” claim should be verified as an AWD R/T Tow N Go, not merely a V8 Durango. Likewise, the V6 can be either 3,500 lb with Light Duty Cooling or 6,200 lb otherwise. The manual’s table also limits frontal area to 40 sq ft for the V6 combinations and 60 sq ft for the 5.7L combinations.

Finally, use the rating as a ceiling, not a guaranteed usable trailer size: do not exceed the vehicle’s GAWR or GCWR, hitch’s stamped tongue-weight limit, or the tire-and-loading placard’s occupant/cargo limit. Passengers, cargo, and accessories reduce what remains for trailer tongue weight.
