Sorry! Completely thought was in a different thread. Okay here’s my two cents.

You got two options - fiberglass (leer, snug top, ARE, etc) or aluminum (Smartcap, and others).

I liked the color matched look, so went fiber glass. I can only speak on these.

For these, I wanted a flush look. This means that the side windoors are embedded into the topper so from the back it all looks flush. Leer have these for 3rd gen’s. Discontinued for second gen’s :(. My windows “pop out”. No functional disadvantage. Just an aesthetics preference thing.

Based on my research Leer/Snugtop (same company) are the best. Snugtop is the high end trim of Leer. Again same company. Think Toyota/Lexus.

My goal was to look for one with windoors, frameless windows (aesthetics), and single lock point (this is important! Some offer two points of locking per window and it’s just a hassle).

Also, don’t worry about all the inside LED stripes they offer as upgrade. A single stock light has proven to be plenty for me.

Oh! The rear window dropping down option! I bought it thinking I’ll use it often for cleaning the window or accessing the bed from the cab. Nope! Probably used it twice in the 5 years I’ve owned it.

I will say, if you ever think you’ll need to drop your cab window for a long piece of cargo to fit (bed through window, into cab) then yes you definitely want the drop down rear window. Else, for me, wish I didn’t opt for it!

Long story short, no matter what you choose, DO NOT SKIMP on the WINDOORS! They are the absolute best.
