Howdy folks, I just became the proud custodian of this one owner 2006 with 12K miles on it. It is completely stock except a K&N filter. The original owner never drove it in rain and changed oil every year with synthetic oil. I Included a picture in case you don't know what they look like. I plan to install a DVD-NAV radio as I want bluetooth, hands-free and a back up camera. I did check the audio/video thread but any input appreciated. So far I love everything about it except one concern: At speeds over 40 mph I noticed the cab get noisy. It just seem to be road noise. All doors close perfect and weather stripping is all there. Any thoughts? Do I have to live with it?
