I've been living in my '87 for a couple of months now full-time, travelling around the western US.  Almost every CA State Park with camping has a shower, a lot of truck stops have showers, I've considered joining a national health club chain for the showers.  Sometimes you can beg or buy a shower from a sympathetic local.
  Where have you found a shower?  Are there unplumbed shower resources of which I am unaware?

                  Somewhat funky in Austin, TX
                  (Need to shower DAILY here!)
