It's bi-fold and only weighs 45lbs from the factory. They wanted 700 bucks for the black unpainted one. It looked pretty durable and will work with the utili-trac. I might have to get on soon. Here's the link http://www.topdawgproducts.com/two_piece.php
They can paint them at the factory to match any color. The factory black matched well with the OEM black. I have to get My oil welfare check from Alaska this year and pull the trigger on one. I hate shoveling snow out of my truck. I hear you witht the dog comment. Thats why I watch DAWG the bounty hunter lol
i think that nissan has discontinued/or at least put a hold on the Hard Bi-Fold cover. something to do with the manufacture that nissan sublets to. Inquire with the dealer, just came through nnanet a few weeks ago.
