Just got a tt ( trail cruiser 21rbh 2867 dry, 5000 gvwr). Don't have tow package but installed a old brake controller for now looking at getting prodigy 2. Got a set of cipa utm's hard to keep tight tho. Getting a hayden trans. cooler. Truck pulled it good on 1'st trip out just went to local park. I know I need a wd hitch with sway control, but do'nt know what tw is can'nt read factory sticker. Thinking I would be ok if I got one rated for 600lbs. Looks like a lot of people use equilizer, also was reviewing the e2. Looks like main differents 4 way sway con. vs 2 way. Any pros or cons?
