If you rely on internet connectivity on the road like I do, you absolutely must become a member of RVMobileInternet.com's "Mobile Internet Aficionados".
The detailed research and technical resources that MIA provides to its members are invaluable, and you can't get them anywhere else that I know of.
And Chris, Cherie and the rest of the MIA community provide help on obscure questions and problems when you need it. My membership has doubtless already saved me many hours and dollars in having to figure this stuff out for myself!
