Nomadic

I know it's a bit silly but I'm quite proud that I came up with the name for our group. It was one of those times when you get a niggling thought that doesn't go away until you actually suggest it. After it received some approval we looked up the definition on wikipedia to see if there was anything we could use. this was the definition for nomad:

 A nomad (Greek: νομάς, nomas, plural νομάδες, nomades; meaning one roaming about for pasture, pastoral tribe) is a member of a community of people who live in different locations, moving from one place to another. Among the various ways Nomads relate to their environment, one can distinguish the hunter-gatherer, the pastoral nomad owning livestock, or the "modern" peripatetic nomad.

While this did tie into our roaming van idea, there was another definition underneath that suited what we were doing perfectly: 

Sometimes also described as "nomadic" are the various itinerant populations who move about in densely populated areas living not on natural resources, but by offering services (craft or trade) to the resident population. These groups are known as "peripatetic nomads".
