Cheap living with style

The time has come or well is coming for me to restructure my life. My son has graduated high school and my daughter will soon follow. This will leave me with 5 acres of land and a house built for a family.I am seriously thinking of selling out the farm and buying a used RV to live in. Some places will let you put in at $100 and some dollars a month with free electric and water.I sure could save up some money fast by doing this. The draw backs are not really having a place to call home and if one of the kids decide to stick around for a while they will have to go where we go. Not a bad deal I love my kids but I can see it getting cramped. Also I was thinking of getting a job a Lowe's so that way if I wanted to visit my buddy M3 for a few months I could transfer to a Lowe's near him (my RV would look good in his spare lot LOL). There are some other places I would like to explore before I die, like Maine. Taking vacations is great but do you relly get to know a place in one week. Also there is the Jersey shore, I could run into snookie. The options are endless. Just an idea.... What do you think would you do it? Cheap RV living
