I've got an EAZ-Lift too. It's hard to know if you have enough or too much tilt to your hitch head by your description?
Here is how my rig looks before the bars are on.
Note that the hitch head has a tilt to it.
When it's hitched up, I have 3 links hanging. I can go to 4 links hanging if I want, but it's too much tension at 4...
I raise the rear of the truck several inches above it's unloaded height to put my bars on. I still need a cheater bar to snap up the brackets. When I lower, it levels me out pretty good and it handles very well towing.
Good luck!
