I have tried to point this out on a couple of threads. It seems there are an awful lot of 1/2 ton and mid size SUV owners out there who are towing trailers that are simply too long... The weight can still be well under limits according to CAT scales and what the TV is rated at, but length of TT has to be factored in. Even if the TT weight is well under the TV capabilities you can still end up with "the tail wagging the dog."
Perhaps to explain it in another way. Imagine having a 400lb block (representing a 1/2 ton truck) on a bar rated for 800 pounds (this represents the vehicles limits), then place a 200lb counter weight block (representing the trailer) at the other end of the bar. Place a fulcrum (this represents the hitch) at the half way point and lift the block. It takes some effort but it can be done. Now move the fulcrum closer to the 500lb block; with the added length behind the fulcrum it becomes easier for that 200lb block to move the 500lb block. All the weights are well inside of set safety limits but physics allows for easier movement of the block with the longer the bar behind the fulcrum. The longer the length of the TT behind the hitch the easier it is to move the truck even though the trailer still weighs within the limits of the truck.
I am merely pointing this out as another factor to consider. I know many people have been towing such lengths comfortably and without a single issue.
I recently traded in my 2002 2500 for my 2015 Silverado 1500. My 2500 was the CTD and it was pretty awesome being able to tow, what, like 15,000lb up a hill without giving it a second thought. The thing is, my new 1500 is the size and capacity of 2500s of old. For instance, the little 5.3L has 355 HP and 383 ft-lb of torque. That's on par with your motor. (Both the 5.3L and Chevy V6 spank my 1995 2500 gasser.) Some days I think back to what it meant to have a 355HP 454 big block back in the day.
Curb weights are also getting dangerously similar. I weighed my truck at 5500lb and you can expect a 2500 gasser to come in around 6,200 - 6,600. I suppose most of this is unsprung weight due to Dana60/70 axles. Obviously, wheelbases are going to be similar.
The 2015 1500 can out tow a 2006 2500 RAM with the 3.73 gears but the 2006 was not tested to the current standard. (The J2807 standard only really came about in 2015.) The J2807 does have a combination handling standard that addresses things like understeer and trailer sway response. The trailer sway response would take into account factors like suspension stiffness, curb weight, and vehicle dynamics other than brute power. 1500 suspensions have come a long way and play an undersung role in towing trailers at this length.
It would be cool to see older trucks tested against the current standard to see how they do. I'm betting nobody would have blinked an eye if I hooked a 33' camper up to my '95 standard cab 2500...back in 1995.
Payloads are admittedly going to favor the 2500s - the hardware under your springs is significantly bigger and better that what's going under a 1500 today. (A painful reminder every time I did brakes, ball joints, wheel hubs, tie rod ends, etc on my RAMs.)
All that being said, I think this is how people are getting away with towing loads with a 1500 that were historically 2500 territory. There is skepticism when people are considering the ratings of late-model trucks but engineers are smarter and materials are better than ever. Some days I wish I kept my CTD but the Silverado is as capable to tow anything my wallet can afford.
To bring this full circle, the 2009 F-150 lineup has similar or better ratings than my Silverado. Again, not rated against the same standard but let's not dismiss the truck summarily based on the numbers on the side.
