It seems half tons only get a bad rap from those who own ¾ and 1 ton TVs. There are plenty of ½ ton owners who are quite content with them.
My F-150 has a max cargo of 1411 lbs. the tongue weight on my loaded TT is about half of that. Two adults and a dog leave about 250 lbs. for camping and truck stuff. This is close enough for the DW and me but maybe not be for a family with kids and lots of toys. The Ram 2500’s I looked at would increase my max cargo capacity by 600 to 900 lbs. depending on the model and options.
Besides the increased towing capacity and max cargo, the larger trucks can offer a more stable, albeit stiffer, ride. All of this can be important if you need it or are willing to pay for it.
You will find the same type of discussion over LT vs. ST tires, the merits of various WD hitches, load range E vs. type P truck tires and a host of other topics. It is not that these larger or alternates options do not offer certain advantages; it is more of a case of do you need it for your particular towing situation.
My F-150 4x4 E-Boost fits my Dutchmen just fine. I am not inclined to mess up what is working.
