Don't think they agreed with you, Nate. Did better up the hill (as JKG said, not surprising given the engine and transmission combo), but wasn't considered as stable or as good at braking. The stability is what I get concerned with the most, having had some trailers get squirrely on me.
Jesse's said that towing his boat (my old boat) that it's barely noticeable. That trailer is rated for 7k lbs, so let's say it's something in the 6-7k lb range. I never had it weighed when I had it. Big difference between that and an 11k trailer.
Personally, I think if you're going to be towing 11k lbs at all you should get a 3/4 ton. It seemed from that report that the Titan XD would do fine if you lived in the flatlands, but get pretty marginal pretty quick in hilly territories. Seemed like 11k with the F-150 wasn't going to be a very good idea at all.
But really, Nate, you just want to get rid of your Ram and get something else. Can't blame you. Your Ram is set up for towing a giant 5th wheel camper, which you've sold. Honestly those gen Rams were not nearly as good of driving trucks as the 3rd and 4th gens (2003 onwards), and without having a need for that kind of capability, you want to get something more comfortable. My Ram makes a nice daily driver. My question would be if you envision yourself having a use for the capability in the future. If so, you're probably better off keeping it unless you want an excuse to buy new, because you won't be able to find a good used one when you're ready to jump back in.
