I do! When we bought our Jayco TT in 2006, research showed it was the best anti-sway, weight distributing hitch on the market. Reese didn't make a unit big enough to support my 1200 lbs on the hitch unit.
We've towed over 20,000 miles with no issues using the Equal-I-zer. Once it was properly configured, it worked like a champ. The Jayco dealer failed to set it up correctly, making my tow home a white knuckeled nightmare. A call to Progress Manufacturing's tech support, and a few emailed photos, resulted in instructions on how to set it up correctly.
Not sure what to do with it now that the Jayco is headed in for salvage. I won't need it with the new Rockwood 5er.
