If you have never done this before, I think going on a six month trip is too ambitious. I suggest starting with two weeks first, and then continuing only if you still feel comfortable. An extreme change of lifestyle is more difficult than you think. I also think that the hermit life has been overly romanticized. It might not necessarily solve the underlying problem, which I assume is your frustration with your current routine. Not everyone is Thoreau or Emerson.
IMHO it's more worthwhile to do something active (a hiking trip with friends for example) in nature than to just isolate yourself. Some of my best memories have been week long trips in nature with a handful of close pals. I remember going almost insane with modern life and seeing all the anger and hatred fade away after a few weeks of physical activity in a new setting.
That said I think your desire to abandon technology for a while and taste freedom is laudable. Good luck to you, sir. All I ask is that you do not abandon human contact but instead seek new people to meet.
