clickyeaz lift install videos are terrible and dont show instructions very well.
The Reese Pro Series is very close to the eaz lift as far as the set up is concerned. I think the eaz lift washers on the tilt head are a little different but close enough. The tilt changes the bars being level to the tt frame.
When you level the trailer, measure the 'frame to the ground' front and rear should be equal height . After you do this and your all hooked up, the combo should appear level. If the TT tongue is a little nose down it will be fine and should ride normal. Some people prefer to have it that way and that's fine. The truck should be close to level as well. If you have too much hitch lift on the rear of the truck the rear tires will spin on gravel or sand. You need to have enough weight distribution on the rear of the truck in order to have traction. After you do this, hitch up and go for a ride. IF you still have sway, then the load and packing of stuff is off as long as your tires and suspension are fine.
** every so often, a specific model (floorplan) of trailer will sway no matter what you do. Sometimes the axles have to be moved rearward an inch or so to offer addition tongue weight but this is rare, just thought i would mention it if all else fails.
Follow the videos method and you'll be fine and this will all behind you. (no pun intended :) )
