2016 SXT hitch cargo carrier advice
I have a 2016 SXT with 145k and need to drive 1400 miles to Miami in a few days. I will have a fully loaded van (solo driver, seats in the floor, and maxed cargo due leftovers from a moving truck), and I was planning on a cargo carrier. I have not driven with a hitch before but can get one installed this weekend. Is this doable for this vehicle, this route, and a good driver (but I have never driven with anything hitched before!). I know a cargo carrier is totally different than pulling a trailer, but still...
My main area of concern for the vehicle with the weight and cargo carrier is southern Tennessee approaching the Alabama/Georgia line (between Monteagle and Chattanooga). There are some long inclines those with emergency truck runoffs. I've driven that route with a van full of people and stuff, but not like this.
Cargo carrier: I was looking at this one from Lowe's that is 60"x24" or maybe something on FB Marketplace.
Oh and last month, I discovered that the radiator was cracked and transmission cooler lines were leaking, so all of that was just replaced in April.
Thoughts on all of this? Thank you so much!
