MTL F7 Mods

I don't really like the old F7 appearance, so a few mods are in order. First I sanded off the bumps that represent horns and got some Sunrise 702's to represent Nathan Squankers (sound like Paul Bunyan stepping on a cow). Made some winterization hatches, and added a few homeade lift rings. Also filled in the lead unit plow and made a dummy coupler.
