2013 F150 XL V6 3.7 wt towing travel trailer

So factory says 5100-6400lbs depending on trim level. But I wouldn’t tow a camper that weighed any more than 5000lbs due to the wind resistance you feel. I towed over 9000lbs of flat stock steel like nothing but my 16ft camper that weighs 5000lbs feels the wind resistance pretty good. You will see high rpm’s and be in 2nd-4th gear most of the time but don’t worry it was designed to rev high like that. The first time it downshifted into 2nd on a steep hill at 6700 scared me but it took it like a champ. You’ll drop from 60-50mph but for a v6 that’s still impressive!!!
