Wow! This hits home. My DW and I have been planning for long term RV'ing in retirement for almost 10 years. Along the way we have enjoyed our yearly almost 6 weeks vacation by taking 2 extended RV trips each year plus many summer weekends as there is no guarantee that a person will make it to retirement (my father passed away suddenly of a rare medical condition at 52 3 years from retirement).
I can't believe how truly fast the last 10 year have gone. I am now 53 and can retire if I want in one year in January 2016 while my wife can retire in 2 1/2 years in June of 2017.
Lord willing, health willing and finances willing we'll retire in the summer of 2017 and become newbie Snowbirds the winter of 2017 for the first time.
Make a plan and stay on it as much as possible but don't live like a hermit along the way waiting for the retirement day as nothing in life is guaranteed.
Happy New year
