We bought the E2 because the reviews were good, the price was right and the lighter rated equalizer was a little too light and the next size up was 1000 or 1200 (I forget). The E2 has an 800# version which fit the bill. We towed with it for one season so far and it seems great. No problem with sway and the TV no longer bounces.
Btw, they're made by the same company.
