Congrats on your tv purchase. Awesome truck, I'm sure you'll love it. I have about 18k miles on my 2018 SuperCab. With regard to towing however, the truck is limited. The Super Crew has a tow capacity of 8,000 lb, while the SuperCab is 6,000. While your trailer weight and tongue or hitch weight certainly aren't a problem for either truck, the limiting factor is the payload. The payload on my 2018 is 700-some lb. Which means after a hitch weight of 450 lb, I have a whopping 350 lb left for people, dogs, grills, generator etc... That's a payload concern, without a trailer!
You'll want to check the yellow sticker on your driver door and get the payload. If you have the Super Crew, that number maybe closer to 900 or 1,000 lb., hopefully.
While you can add airbags or change leaf springs, too stiffen up the "baja rear-end" that doesn't change your payload number. Do you know what your loaded tongue weight is?
