Another vote for the Equal-i-zer here. I used a Reese standard old style bar with the attached chains with a separate friction sway bar for years and years. It worked well on 3 different travel trailers, a Surburban, and 3 different truck combinations, until the hitch head bent (simply old age I think).
I then switched to an Equal-i-zer (mainly because that's what my RV dealer pushed and recommended for my Outback TT and 3500 duly). So I went with it. My dealer set it up for me, and after a very short while, I realized it was so much easier to hitch than the old Reese "ball and chain" and performed great, and didn't have to mess with the separate friction sway bar, I realized I liked the Equal-i-zer so much more!
The Equal-i-zer did make a lot of noise, popping and groaning when it was first installed. I did eventually get the little pads that go on the L brackets and it quieted down tremendously without changing performance at all. So if you go with Equal-i-zer, get the little pads that go on the L-bracket from the beginning. They don't cost "that" much and in my opinion are well worth it.
