Just like to say, thanks for all the information I have been able to read over the last couple months. I have just recently registered and making my introductory post. A little information about me..... My name is Anthony Fields. I live in Grain Valley, Missouri. I have a 2006 Commander limited. I absolutely love this thing, compared to the Envoy I had before. I got the Commander stock, but it did have an aftermarket head unit. I have since done a 2" rough country lift, 1.5" wheel spacers, pinch weld mod, interior door handles, some running board/side steps, LED headlights/fogs/backups/and interior. I put some wrangler sahara wheels and tires on, and added a roof rack as well. I am quite sure there are other little things I'm forgetting, but again, Thanks for all the information because I will most certainly be needing more real soon!!
