I have used the newer Blue Ox Sway Pro on my last two Trailers. I have used Equalizer, Husky, and Reese in the past, and like the Blue OX Best so far.
1. Zero sway (all built-in control) Actually saved me several times when run off the road onto the shoulder and pulling the TT back onto the pavement at 60mph) Completely quiet even when backing up.
2. Quickest hookup (once adjusted for your TV) the Roller cam for the chain in brilliant design) No loose parts (no pins or bolts)
3. Always clean (powder coated and sealed grease fittings)
4. Can be used with 5k to 10k TT's by simply changing the bars
5 Very heavy duty
only downside..heavy and yes expensive (around $700) but cheap compared to a Hensley or Pro Pride.
