Well, No, Man if i did not have a cabin, I'd have the OR 4X2 and a shrockworks bumper with a winch. If you lock that rear, You'll go anywhere a 4x4 will and what you have problem with the winch will bring you over. Plus, you save on Gas and weight. Keep what you have, Mod it up, use it until it's time to switch then decide what way you will go.
If they come out with a locker, you are in business! If not, get that winch anyways! You'll be capable! The right tires... Go for it!
Like Dan said, you'd be up side down right now. So live with what you have. I sure won't be dogging you for it! Like I said, If I did not have the Cabin, I'd have a 2X4 and a winch.
