Ok, I have searched but can not find anything. Is there somewhere on here that lists all of the abbreviations used on the forum. RMW, I think I figured out that I have one. I assume it is Road Master Wagon. In fact, I think I used it a couple times, I hope I was right on its meaning. Thanks guys.cwm3

I prefer OCC to CCW. As a result of being on a few gun boards I automaticly assume someone is talking about their carry gun or permit...

Dont forget RTFM...

ETA: Comes in handy on occasion.
