I've read on another thread on here somewhere that it is not recommended to have the hubs locked but T-case in 2H. It was something that I had wondered myself and then somehow stumbled across that thread. Can anyone clarify this?

Because I just came back from a road trip with bad winter roads and getting in and out to lock and un-lock the hubs is a pain in the ***. If indeed it will cause no harm...I'll be happy to never have to do it that way again.
