I'm guessing how long you've been a member plus number of posts.
I never paid attention til now, but I've been a member (Sept 2012) a year longer than you (Sept 2013) & you've posted 16 times to my 2764. So I need to shut up or you need to speak up!
I just sold my '13 FB, took delivery the day after Thanksgiving 2012 & traded our Denali 3500 dually, so for now rvless.
