I'm simply re-uploading this long lost Z71 Suburban mod, made by nik287 & GROSS. AFAIK, neither the civilian or FBI versions are no longer available for download, but I found the files while cleaning up the hard drive.

And just in case you've been wondering, "Read Me" file is indeed authentic, but the model had to be extracted from the game, IMG archive which is why neither date or time stamps are no longer original.
