Had a 27' TT that I pulled with a F250 4x4 extended cab long bed for several years. Used Reese Dual Cam. It pulled good and generally tracked fine. Never had a "nail biter", but I did find myself anticipating trucks passing me. The fiver, for me, tows much better. Yes, I setup the DC correctly. Being an engineer, I studied it greatly. Not saying the TT was bad, but if I went much bigger or towed a lot more, I would look at a different hitch such as the HA. The one thing I miss about the TT is backing up. I could put that thing anywhere I wanted to on the first try. The fiver does take some getting used to. As other have said, the reaction time is slower, which means you have to anticipate what will happen and react before it happens. I like the floorplans of the fivers, hence own that now.
