I have to agree with Texas_Camper - the FIRST thing you need to do is get the hitch ball up to a reasonable height. If you don't, it will drag at every opportunity. Whenever it drags, it puts tremendous stress on the entire hitch assembly (including the hitch receiver on your Lexus), and after a while, the welds will come apart and you will lose your trailer!

I have the same (or very similar) Reese WD hitch. It is easy to raise the ball height. Quoting from the Reese web site under "Weight Distributing Ball Mounts":

"* All REESE adjustable hitch bars can be used in raised or dropped position." Just flip it over and use it in the raised position. Your hitch probably looks like the one shown in the page below, which is from the Reese manual.

Once you have raised the hitch ball, the SECOND thing you will want to do is raise the trailer frame and body with a lift kit. As has been pointed out, a lift kit will not raise the axle, but as long as you stay on paved roads, that's not really a concern. What is of concern is that when you raise the front end of the trailer, the rear end will drop and you will start dragging the rear bumper. This is annoying, but not nearly as damaging or catastrophic as dragging the hitch assembly. And a lift kit will take care of it.

PLEASE don't drive around with the hitch assembly only 3-4" off the ground. It would make you a menace to everyone else on the road, as well as yourself.
