I just got this rack a few days ago.
http://www.etrailer.com/Merchant2/merchant.mv?Screen=PR...04&Category_Code=CCR 4ft x 4ft. Just what I was looking for to tote my spare tire. Only problem is hefting that sukar up there when I take any kind of trip out of town. Not to bad, got a couple straps to hold the tire down. Tried to post a pic of my truck with it on ,, But no can do -- error issue
