To assure a minimal expense journey you must think about areas to stop along the route to and from California or Arizona. You should plan your route ahead of time and locate rest stops and truck stops along the route that could be used as overnight resting areas. Some of these provide water and sewage disposal stations although the most northerly ones, in winter, sometimes have these provisions turned off due to freezing.

The following information was accumulated on the routes that I have traveled to and from British Columbia to these boondocking areas.
