Depends on how far you are going and weight distribution. I towed a 1,200lb dry weight 5x8 cargo trailer with about 1,100 pounds in it from Olympia WA to Tyler TX.
Gas mileage was horrendous and with the small tank, in Nevada I was filling up every 100 miles. I put the heaviest items over the trailer axles and the car still rode high in the front. I had to redo the load 3 days in. I couldn't find a way to turn of the rear warning sensors so every time I backed up the car would scream at me.
That engine was a star and I had no power issues. I wouldn't do it again that distance. 2018 Platinum.
I tow a travel trailer with my 2017 Ford Explorer Sport (Twin Turbo 3.5V6), fully loaded I'm just over 4,000lbs. I get about 12 mpg when going to from the Phoenix area to Flagstaff which is 5,000+ in elevation change in 2 hours so it's a decent climb. No power issues at all.
