I love my bull bar and had the same question when I got mine. I think the chrome works, but it's a matter of personal taste. I also like the black, so I don't think you can go wrong either way. Either way there's no more work to cleaning my chrome bar than a black one. I will dry it when I dry the truck and put wax on it just like I would if it was black, but nothing else additional. Good luck, when you get it post some pics.
I really like the look of your truck. I've been thinking about adding a bar to mine, now that I've seen it on another black truck I think I'm going to start saving up for one. I just don't know whether to get the black or chrome one. I'm lazy so I figure black would be easier to keep looking clean than the chrome.
