Hi i am new to the site, have ordered a 06 GMC 2500HD 4x4 ext cab and reside in Australia truck due December 06 i have just seen the new 07 on the internet does any one have any info re the difference a couple of things i have heard or noticed are the rear coils instead of leaf springs, also i am told the emission is tougher, as i am in Australia the trucks drive have to be change over and i am told that the parts might not be avalable to do that until 2008 but sure would like to have the coils on our bush roads out here.
Regards
