As the 3rd Gen area has become busier and busier I'm becoming more stringent on keeping things categorized. It's simply easier to read through the posts and they get better replies when in the correct area.
The most common post to get moved are Products/Accesories related. There's lot's of Cummins owners who have studied various lubricants, gauges, exhausts, etc, and most of them not 3rd gen owners so there's a-lot more info available under the Products/Accesories forums. Early-on when hardly anything was available for 3rd Gen I allowed a-lot more posts to stay in 3rd Gen simply because everyone was trying to find 3rd Gen specific vendors. Now most vendors have caught up.
