I like the idea of encompassing the whole region in your name... North East Rollers, New England Rollers... doesn't really bring into play what you do though... but it isn't a "Jeep Only" name... Northeast (or New England) Off Road Rollers has a nice ring to it... My personal opinion is to stay away from Off Road cuz we actually don't go off roads, we stay on them... we go off highway... but... its so easy to use and sounds good in lots of names....
Does that help??
Talk soon,
