Welcome to the CRVL Forums
There is plenty of information here and people versed in almost all aspects of this way of life.
You just need to lurk for awhile and determine which way you would like to go about it.
If you are going to be flying solo (single) a smaller vehicle such as a Van, Shuttle Bus, Short School Bus,
or small used RV may get you on the road affordably, quickly, and comfortably for your first experience.
Your first few months out there may help you figure out what would work best for you. Some meet up's
and Camping with others in a State or National Parks may be informative too.
You are welcome to view my websites below for any ideas you can draw from them. The first one is how I fit out
my first Rigs, and the second is for when you hit the road and find that you need information about anything from the weather forecast to locating cheap gasoline or where the laundromats are. But it can make your travel experience easier and more enjoyable.
All the best !
