Automatic hubs have came a long way but I still won't own a set. Manual hubs are stronger and you know whether it's locked or not. No guessing. Manuals are more reliable, too. The only downsides to manuals that I can think of: 1. You might get your boots muddy. 2. Ice can freeze on them, get a hammer.
What year are your dodges? Most of them don't even have hubs, stub shafts turn all the time. Just have a disconnect in the pass side axle. Wife has one, not impressed.
I have two different vehicles that have manual hubs. Had a Ford with auto hubs, and they went out at a bad time (during a 12" snow last winter). Cost me about $500 to get them repaired.
Manuals are just more reliable.
