I am guessing your E2 doesn't offer enough sway control. Which model do you have? Getting a 4pt sway control hitch if you don't have one may help a lot. I have a husky 4 pt sway hitch and I have ZERO sway towing a trailer roughly the same size as the OP. Conversely, my Passport was less stable than my current trailer (Passport was about 4.5 ft shorter); I was running an Equalizer 2 pt sway on that unit.
