Thanks for the comments. I am thinking about doing some slight weathering on this model with the airbrush and some slight washes with some mud and dust. There is an old cabover truck a few miles down the road I might go and take a few pictures of for refrence. I was also going to go down to the truck stop by my house and look at the trucks but I do not want to break any laws or rules or anger the truck drivers for looking at their trucks.
