Apparently any time in any thread it can devolve into 2wd vs 4wd.
Somehow we had 2wd trucks for decades before 4x4 became popular with people that use trucks for something totally different.
Excuse my ignorance but one thing I've never really understood though is why 2wd gets, or should get, better mpg than a 4wd. I mean when the 4wd is not engaged why shouldn't it get the same mpg as a 2wd? Help me out brothers....
