I have a 2016 f250 super cab long bed 4x4 with the 6.2 gasser. I just ordered a 38' intech gooseneck trailer. I figured it will be around 12,000 lbs fully loaded. So it is within the rated towing capability of the truck. But I am worried that it's just not going to have enough power especially living in western Pennsylvania with the hilly terrain. So I am looking to see if anybody has real experience pulling a trailer like mine with the 6.2. I looked and test drove a 2021 f250 diesel today and they offered me 35,000 for mine . But if the 6.2 will be enough then I am happy to keep it as it only has 14,500 miles.
