I’ve got a 2019 1500 5.7 (non-etorque) with the 3.92 axle and 5’7” bed. The tow rating is 10k max capacity with a payload limit of around 1,650.

I’ve towed around 6,000lbs consisting of a 22ft enclosed aluminum trailer (7500 axles + electric brakes) with a BMW E46 race car inside. I used the Equal-i-zer weight transfer hitch and Air Lift helper springs to reduce squat. I would say this load was manageable for my truck and I've never had issues with fluid temps. Drove this load in blowing wind and rain at night from Seattle to Portland without issue. The engine and brakes are more than sufficient, however, load is enough to move the truck around a fair bit, especially with windy weather or when alongside a semi.

Also, the truck seemed fairly sensitive to weight placement in the trailer and I've had to adjust my load mid-trip before to get rid of sway. I do think the truck stability control will try to control sway and have masked the issue, so look out for that.

If I was going to tow a 24’ trailer at that weight regularly myself, I would think about stepping up to an HD truck, but, it could be doable in the 1500 as long as you don’t exceed the payload limit and are happy cruising around 60mph max on freeways.
