I would recommend the 4-point Equal-I-zer. The e2 is good, but the original has better sway control and a trailer your size should use it.
The Reese Dual Cam will do the same job. Many happy campers tow with both.
What is your truck? With a dry weight of 8800lbs, your loaded weight will be closer to 10,000 plus lbs and I'd venture your tongue weight will be 1,300 or so.
The best WDH options are the Propride and Hensley.
