The aging of the present RVing group is certainly a major factor with the next generation not coming into the life style in as large a number as in the past. We have three friends that could no longer travel due to health reasons who offered their RV to their children free of charge and were turned down. They now are trying to sell their rigs on the open market.
For Canadians there is the added factor of the increasing cost of out of country emergency medical travel insurance that keeps rising yearly as you age. The DW and I on fixed incomes are in that dilemma now and do not know how much longer these insurance costs, lot rentals and travel expenses will allow us to continue. It was a close call this year.
