Trailer Life towing specs are copied from the Ford RV and Trailer Towing Guide. Those specs are extremely optimistic because they assume a tow vehicle with no options not required to achieve that tow rating, and absolutely nothing in the tow vehicle except a skinny driver.
My 99.5 F-250 had a tow rating over 13,000 pounds, but I was overloaded over the payload capacity of my F-250 with my 25' 5er with one SuperSlide that grossed only 7,900 pounds.
My current F-150 has a tow rating of over 8,000 pounds, but I'm overloaded with my 21' TT that weighs less than 5,000 pounds when wet and loaded on the road.
So ignore those Ford tow ratings and determine your own. Weigh the wet and loaded rig, with you and everybody and everything that will be in it when towing. Load the trailer with everything that will be in it when towing, including any fresh water you haul to flush the pottie when on the road.
A CAT scale will give you four weights - front axle, drive axle, trailer axles and gross combined vehicle weight. Add the weights on the front and drive axles and compare to the 10,000 GVWR of your F-250. Compare the weight on the trailer axles to the combined GAWR of the trailer axles. Compare the weight of the gross combined vehicle to the GCWR of your F-250.
Through over 15 years of being a moderator on TheDieselStop.com (forums for Ford diesel truck enthusiasts) I've learned that around 12,000 pounds is the limit for most people with the most popular F-250 tow vehicle = PSD, 4x4, CrewCab when hauling their normal family, tools, options, and campfire wood as well as the trailer without being overloaded. Like me, they cannot get close to the GCWR or tow rating, because they run out of payload capacity before they load the trailer that heavy.
The tow rating for a travel trailer is limited by the weight capacity of the receiver hitch. So you care about the tow rating for a 5er. Your 5er tow rating is 15,100 per the 2015 Ford RV and Trailer Towing guide. But even that tow rating is still exaggerated, as the CAT scale will prove.
