thats the one i have on my truck. i love it. never a single problem. takes up maybe 3" at the front of the cab, but only at the very top. i do lots of hauling, and it has never been in my way. and if you want to take it off, just 4 quick bolts and its out. heres a couple pics of it installed:









edit: i have never had a problem with it flapping in the wind too much either. there is a dial at the front to adjust the tightness of it, works great. and the velcro is still rock solid after over a year. and i dont see it failing anytime soon. and if it does, the cover and all components have a lifetime warranty. and lastly, the weather seal is awesome as well. i have never gotten more than a couple drops inside the bed during the harshest of rains.

 

I just put the access vanish soft low profile cover on my 08 ram SB and it takes up about three inches max in the front of the bed rolled up. It looks great its easy on the wallet and it was easy to install.
