I have done Internet research on working from an RV and even found a library book on the subject, but they offer vague and similar advice: freelance writer, blogger, photographer, repair man, temporary nurse, multi-level marketing, online business, workamp situations (www.workamp.com), looking at coolworks.com for short-term opportunities, etc. The best I read about included working at a National Park and volunteering for Habitat-for-Humanity that sometimes included a free or discounted parking space -- both of which I want to do, but are more for the fun of it.
The first avenue to explore is online consulting or short-term fill-in work for non-profit organizations in need of fundraising support. (My pre-SAHD career) I could either offer an on-site fresh set of eyes or offer temporary leadership in-between their former chief fundraiser and the next. I figure these assignments would last from one week to several months. Regardless, the pay would be sufficient and we could just relocate and explore along the way. I don't think there are any fundraising consultants currently practicing in this unique way. I've also contacted my alma mater in the hopes of working with them as an on the road representative.
If these ideas don't pan out, our other options include my wife working on curriculum for people who travel and educate their kids (she is an early intervention specialist in our local school), scrapbook consulting, take and sell awesome photography along our journey, develop our Send Out Cards distributorship (www.sendoutcards.com/growrelationships) that we have largely ignored for several years, write & blog, teach online, tutor online, etc. I think we may have enough to piece together our finances.
It seems there is much to plan and get ready for and we may be a few years out. So for now we will keep exploring, and keep cleaning out our house. It is amazing what our small family has accumulated. Just the act of slowly cleaning out our belongings will help us stay on track. Our new motto when faced with purchases big or small will be "would we rather have this or the RV?"
