Getting ready to full time and DW is getting nervous

Real interested in full timing and bookmarked tons of blogs and other stuff. Came to the conclusion most of the folks looked to have a pretty good financial port folio to fall back on. On SS and a very modest savings and IRA we would have to sell the house and all my stuff that has be acquired over the years. End up not liking FT or grow to old to enjoy it and not having a house is a pretty scary thought. Thinking of alternatives. Having two places and splitting time doesn't seem to cost effective.
