Need help creating "Big Rigs West"


Does anyone have any ideas on building a data base that would presumably require input from multiple people? I have been using Streets and Trips feed up to my dash in my MH on a 15,000 mile trip. I rely on the location of KOAs and Big Rigs East , data bases downloaded from the POI-Factory, to decide where to stay each night.

What I really need now is locations of big rig campgrounds west of the Mississippi. I could contribute a couple dozen myself and maybe if others were interested they could do likewise. Have any of the POI databases been the result of collaboration between many users? How would one go about it?
