Towing a travel trailer is a wake up call for people if they have never pulled one before. The trucks behave totally different pulling a TT than pulling a flatbed or a utility trailer or even a boat.
So, with that said, you will feel that drag behind you no matter what kind of small block truck you get. Even big blocks and diesels feel drag from the trailers.
The big block recommendation is great and there is a reason they were towing kings for years.
However, your truck is probably more than fine. People have been towing those weights with the 3.43 and 5.3 for years now. You will not hurt the truck just let it work and let it do it's thing. Cut the OD off and stay in the slow lane. 60-65 is pleanty fast enough and on hills it's normal to lose a few MPH while climbing. Many of us half ton towers do just that and have for years.
If you are the type of persons that expects the truck to accelerate while towing just like it does unloaded then the 6.0 1500 HD will disappoint you. Because it will be very similar experience. The truck will behave one way unloaded and another when loaded.
Higher RPM, slower speed, feeling the load behind you, losing some speed on some hills is all perfectly normal and part of the natural experience of being an RVer. Even Motorhomes do that to a degree.
You just need to decide what you are willing to find acceptable and what you will not.
