JMHO, I think most average full timers are intimidated to post what their cost is. Consider that the average SS check is only $1229 a month and many people have no other source of income. Lots of PA and Escapees members, discount clubs, BLM permits, and boondocking. It takes all kinds and there are all kinds of budgets.
Nothing wrong with spending 72K a year but how many rvers really have that kind of money? I think it falls into the 30K or less per year and you can even see the low end:
$500 and $1000 a month fulltime budgetIf you only have a budget of $200 a month for fuel and your tow vehicle gets 10 miles to the gallon at $3.00 a gallon, that is about 650 miles a month. You would probably move once a week or less. Fulltiming isn't a cross country race for everyone, it can be a slow moving adventure that takes you from one area north to south to maintain warm temps year round.
