That is a nice looking bus you got for a very reasonable price!
As you prepare to start your adventure, the more your bus does not look like a converted school bus the easier it will be for you to do stealth camping as you tour the country cooking.
Something 35' long, 8' wide, and 10' tall is hard to miss when it is painted National School Bus Chrome Yellow. The same bus painted in almost any other color or combination of colors will fade into the background and will hardly be noticed by other people who are not bus nuts.
