Yes they do, with the windjammer on you can only slightly recline the seats. Same with the duster cover. i use the duster cover all summer, you can get away with a little bit of recline when it heats up in the sun, but thats about it.
I got 99 Problems but a Jeep ain't one
I have a duster and windjammer. My seats are reclined and pushed back pretty good, yes there is a gap (sides and top), but it's no biggie. I run that set up all year long, it keeps the AC and HEAT trapped in pretty well. Hope this helps.
If you're 6-2 or talller, it's likely to make your seat position uncomfortable. I'm 5-11 and while my seatback is pushing into my Windjammer stretching it back a tad behind my seat, my seat position and angle is fine.

Thanks guys, this helps alot. I am 5'10" so I dont sit back ridiculously far. I will probably go with the duster cover so I'll feel more comfortable leaving stuff in the back with the top down. I'm not sure bout the wind jammer yet. Thanks again!!
