You don't need to drive around in 4wd, just engage it for a minute on a straight away (4hi is fine) then go back into 2wd. I use mine regularly for hunting or fishing but once a month is plenty just to prevent things from sticking.
Unless I am missing something, there are no electronic locking hubs on the new trucks....the hubs is always spinning the axle shafts. The only thing that changes is in the diff, where one side is disengaged until you put it in 4wd. That is the only way you can put it in 4wd hi at speed and NOT destroy a gear or shaft.
