Welcome to the CRLV Forums
With that kind of prep and research time you'll have an excellent chance to land on your feet once you take off.
With the spring season upon us you will be able to yard sale and flea market to find many of the things you would want to outfit yourself with for cheap too. So do take advantage of your timing.
I didn't notice you stating if you have a vehicle you intend to use for this yet or not. But in the "fall" of each year when the new model year vehicles begin to arrive at the Car Dealerships, people begin to sell their older vehicles and you may find a great deal then.
If you need to sell off a lot of stuff that you have that's just sitting around you'll have plenty of time to liquidate.
As for planning how to go about your travels, the bottom link below is a Portal of info to use to plan with or once you are out living on the road, to navigate in our travels.
All the best !
