Jay,
As tigger mentioned, the ProPride (and Hensley Arrow) are the top wdh systems, but at a premium price.
The next level of systems at a more reasonable price is the Reese DC, the Reese SC, and the Equal-I-Zer 4 way system. I have been reading very good reviews of the Husky Centerline system, and the Recurve R6 as well.
The one thing you need to make sure if with the new style DC is that the cam arm brackets are mounted properly.
Here is an extensive thread regarding the issue and proper mounting over on RV.Net forums. Unfortunately some of the pics no longer show up though.
I have been happy with my DC, but did have this bracket issue due to the dealer not mounting them correctly. I actually found an old style model (u bolt like you had) that was still brand new in the box and that is what I am running now with the new style wd bars.
The Reese SC and 4 way system are very similar. A couple advantages the SC system has over the 4 way is the hitch head is able to be adjusted more, allowing a more finely tuned in tt if needed. Look at a pic of the hitch head and you will see the fine teeth on the side of the hitch head. Also, the wd bars can be replaced if you change trailers, where with the Equal-I-Zer system you can't swap out just the wd bars. BUT the Equal-I-Zer system is made in the U.S.
I have never owned the CL or R6 systems, but a buddy recently got the CL model and it seems to be a good hitch. One complaint I did read of the top model CL is that you need to be in almost a straigh line to hook and unhook the wd bars. And it's heavy!!! But what wdh is light besides the Anderson system. The R6 also seems to be a good system, but I haven't read as many having it as the CL.
Just make sure to choose the correct rated wd bars for your loaded tw, and if you need a refresher on how to adjust the wdh, follow my signature links for a how to.
Good luck shopping!!!
