I am looking for a complete roof rack system for my 2011 silverado crew cab. I briefly looked online and it looks like no one really sells a side rail and cross rail package together. From gmcaccessoriezone.com, side rails are $179.00 (part # 19166253) and cross rails are $189.00 (part # 12499404). I was not looking to spend $368.00 + tax. If anyone has them on their 2008-2011 silverado and needs some $$ or anyone knows a place/website/idea to get a MUCH cheaper price, please let me know. Thx.
