Since we stopped full timing, we usually spend four or five months in Tucson, and several months elsewhere, and three to six months in our little townhouse.
This year, we were in Tucson on January 1st, and got back to our townhouse in the middle of June. We plan to hit the road sometime in October. That will make the total for this year around 240 days in the RV for 2014.
Some years it's less, some years it's more. It's usually based on when and where our friends and family are doing something we want to be part of. The birth of our next great grandchild (not yet scheduled :) will be near the highest priority level.
