So Plowed & Repo Duty

These castings look fairly visually similar, they are both white on top and they are both blue down below, and they are both trucks made for specific jobs. Anyways, this should be obvious, but the snow plow truck looking one is the So Plowed while the tow truck looking one is the Repo Duty. I don't think either one is too popular for collectors but I still wanted them in my collection!
