I am running a Trekker by Eaz-Lift WDH on my 2010 F150 pulling a Roo 23 IKSS. Could not be happier. No sway whatsoever, nice level setup and no disconnecting to back up. I like that it does not use chains so it is very quiet. Also, you can disengage the sway component if you want without taking anything off. It has these large bolts/caps to turn the sway on and off. I will loosen them for very tight turns when backing.
I did a 5000 mile trip last summer with no problems on freeway or mountains. Hitch weight about 600#, trailer weight about 6000#, truck capacity - tow 9800#, tongue wt. 1200#.
