The Equalizer is the same as the E2, now made and owned by the same parent company. If you think one is better than the other, you're being tricked. Both are very good traditional, no-chain, friction based, HIGHLY adjustable WHD options.
The Dual Cam is a step up IMO, mechanically speaking, is a different animal and is a more effective WDH. Not covering poor set ups, but apples to apples better than the E2 and Equalizer. Do you need this? Well, IMO I think larger trailers benefit.
25' is middle of the road average for bumper pull TT's and being pulled by a larger SUV one could easily could go either way and never look back.
EDIT: Forgot to mention feedback on PP and Hensley. Their mechanism to eliminate sway is the real deal. The best bumper pull set ups will see an improvement and at insane towing speeds feel rock solid. (That's coming from my actual experience...not assumptions). Not many will actually need such a hitch, but if one really wants a 5th wheel like towing experience, these are your only two options besides buying a 5th wheel.
Question is , is the price worth it for the amount and distance you travel? For most the answer is...NO.
BTW....for a time I was torn between the two competing companies with no clear winner. But I now have a crystal clear opinion...and its Propride.
