RPO code question
 

My truck(in signature) includes the RPO code "E6C." This translates to "Country Gambia." What does Gambia have to do with my truck?

Looking further through the rpo codes list, I see that quite a few of the E6* and E7* codes are used for obscure country names. Small African countries dominate the list. I don't see any of the larger, more well-known countries showing up on this list.

I think E6C is the GVW code for 8600 lbs. at least that was one reference I found.
