I have researched this myself as I have the same truck you do. The reese 2 1/2 inch draw bars do not work with the round bar hitch head. I did my research through etrailer.com. I have trunnion bars now but I want the bigger draw bar. My hitch head won't work for different reasons. I am buying the bigger draw bar and the Reese dual-cam set up later this year. I use friction sway control now. Tows fine, just want bigger and better. I agree on the noise, every time I make a turn, it shifts and makes a huge clunk noise with the adapter.
