To the OP: the centerline, Blue Ox, Reese Dual cam and the Equal-i-zer 4 point have all had good reviews on the RV forums. All four work well. It is a tough choice but you can't really go wrong no matter what you choose.

The part of your post I am taking issue with is when you state" if your tow vehicle is marginal." You don't have a perfect towing setup and then cross a line where you need a ProPride. I think any rig you can tell a difference when towing with a ProPride. As TT size and weight increases toward the tow rating of a particular TV, I think you will see a much greater increase in hitch performance with the ProPride- which I think might be kind of what you are saying. I've towed with a standard chain type hitch with friction bar, the Equalizer 4 point, and now the ProPride. There was an improvement with the Equalizer over the standard, but the difference in those to the ProPride was VERY apparent. And I towed with these on a 97 F250 PSD, a 2011 F250 PSD and now an F150 Ecoboost. Once again, I THINK we are kind of saying the same thing- if I still had the F250 PSD, I probably wouldn't opt to spend the money on the ProPride. However, I don't consider my F150 Ecoboost to be a "marginal" TV. I hear of a lot of people (even with 3/4 and 1 ton trucks) upgrading to a 5W and a lot of people upgrading their 1/2 ton to a larger truck because of sway issues they are having, even though they are under published ratings. Those upgrades typically run $10K to $20K+. I think they could have spent ~$2700 and solved their problem. Used ProPride hitches typically sell for $1500-$1800, so the majority of that investment could be recovered later, too.
Edit: Just reread your post and saw the statement of "even if your setup is ideal.." so, apparently we are somewhat saying the same thing.
