i think it's a good idea, apart from that i would suggest a subscription system for VTCs.
why not make some money with truckersmp, on a "you don't need to pay to play, but you get your own VTC paintjob if you do" basis. i.e. 10€/10 driver slots per year or whatever you can think of.
this money could then be used to upgrade servers/connection or anything needed to develop truckersmp further (and other improvements).
have each VTC have a required "spokesperson" who ensures that all drivers are driving safe and abide by the rules, if not they're kicked from the VTC.
all paints obviously need to be reviewed (to avoid the swastikas and handdrawn penises ) and have certain requirements (i.e. resolution, "a realistic look", no country flags or "patriotic" slogans etc.)
the biggest problem is the "too many VTCs" thing, but i'm sure there will be solutions to that...
