Am I right in thinking that this top can't easily be lowered all the way like the factory soft top can ? I'd like to be able to fold down the soft top the entire way. I have the OEM soft top, which allows me to do this, but I like the look of the slanted rear. Is there a soft top that has a slanted rear and allows me to fold down the top completely without a bunch of hassle ?

The Trektop doesn't fold. It's more like a giant piece of fabric that stretches over the rollbars and is secured via a header, a tailgate bar, and inserts along the side windows. It's like a baseball cap for your Jeep.

You can roll the front part back for a sunroof-like effect, but the Trektop definitely doesn't fold like the factory soft top.
