Take a look at RV-Dreams
dot comThere are several books out there on fulltiming too. Complete Guide to Full-Time RVing: Life on the Open Road by Bill and Jan Moeller is one.
Our basic formula (and it varies according to your situation and desires) was:
House Paid Off. Bills Paid off. Debt-Free.
Financials - what will your income be and how your expenses will be met - including rv, auto, and health insurance.
Started downsizing our belongings five years out. We didn't need all that stuff. Yard Sales every year. Donations to charity. Gifting to relatives. De-Clutter - it helped when we put the house on the market. In fact, we moved out and only had furniture and a change of clothes left. Since it sold in 5 days, all that prep work paid off. Had a furniture sale the weekend before closing and we were ready.
Also about 5 years out we shifted our bills to email. Got on all the do-not-call and no junk mail lists. Closer to freedom day we canceled any magazines we had left. We examined all our incoming mail with a view to getting it in email or getting it discontinued or sent to our po box.
Formulated an "exit" plan. In our case, we knew we wanted a retirement house out west and needed to buy before the real estate market took off again. We banked the money from the sale of our house and added to it as we traveled.
The first year you will probably put the most miles on. Dream trips should be taken sooner not later - who knows how long we have on this planet?
If you are wanting to augment your income, investigate "work at home" jobs and workcamping. If you are into volunteering, state and national parks give an RV site for seasonal volunteers.
Save as much money as you can. That advice is good no matter what age or circumstance you are in.
:-) ok - there is my brain dump.
