Dustin,
First off, welcome to the RV Forum; glad to have you here.
Regarding your question of costs: it's a little too vague to give any kind of specific answer. It pretty much depends on how 'high on the hog' you want to live. Some folks spend most or all their time in free or low cost federal, state, local, private areas, don't eat out often, spend little on entertainment, and don't move from place to place much. Other prefer to locate in high-rent rv parks where everything is provided for them, don't cook their own meals, etc. You get the picture. Cost of the rv is another consideration. Buy big and new and you'll take a big hit on depreciation but get exactly what you want (maybe). Buy older and used and the depreciation is down, but maintenance may be higher and things may not be as large or convenient as you would like. Bottom line is that you need to decide what kind of lifestyle you want to pursue, and plan accordingly. Everything in life is a compromise; you just have to decide what you absolutely need and what you can do without - then calculate costs from there.
