"OP, are you selling your home and "taking off", or are you going on a "walk-about" for several months?"
We're renting it out for a year...so we have something to come back to if this doesn't work as expected.
My wife loves to grill and cook so we will most likely eat in the majority of the time. We are in no hurry what so ever, so staying in one place for a week or two is not a problem..there is so much to see that I don't really anticipate driving much more than 100 miles at a time (until we get out west) if that. "Work camping" could be a very good option...
Thanks to everyone that posted - makes me feel much better about the budget
