I too use all and star at the newest and work down. I hover over titles that are iffy to read the first few lines. The title of the Topic is more important than Gas vs. Diesel. Putting compression brakes in the title gets to the right target, up front. I also like reading diesel topics.
I and many others also have gasser which span some of the above listed categories and items. I have an inverter/charger (granted it is a small one), 22.5 wheels, genny is a 7.5k and 50 amp rig.
So I say leave it alone and use good topic titles.
