ZEUS, the Trooper t-case has the 4LO lever only just like us, 2WD is just the TOD turned off and the front axle disengaged. if your looking for minimal parasitic loss I'd go with a fully mechanical t-case, and ditch the TOD. getting the Trooper TOD system to work with manual huds just seem like a lot of work. I don't like the idea of having to get out and locking the hubs when i have the sudden urge to get the old girl all dirty.
