Here is another tip volunteering. We've been fulltimers for 7 1/2 years and volunteer 6 mos three somewhere up north in the summer and south in the winter. This cuts our site expense in half. These volunteer positions can vary fron manning a visitor center, interpretive host (training provided), camp host which duties may vary from agency to agency. We started at state parks then USFS, USACE, and USWFS. Hours required vary but the work is more enjoyable than difficult. You may want to check Volunteer.gov and any state DNR page and look for volunteer opportunies.
