I have used both the Equalizer (4-way control) and the Reese Straight Line. Both are very good systems and in my opinion perform equally as well. I prefer the Equalizer simply because I found it to be quieter and easier to setup.
I don't know which Equalizer hitch the dealer is prepared to sell you, but you will not be disappointed with the original 4-way control Equalizer. I have no experience with the new E2 system.
