A trailer includes a front section having a first floor with an upper surface at a fixed vertical level approximately between three and six feet above a street level, a middle section, and a rear section having a second floor with an upper surface at the fixed vertical level. A horizontally-oriented platform is disposed in the middle section. A lifting mechanism is coupled to the platform and selectively raises and lowers the platform between a lower position of one to two feet above street level, otherwise known as curb-level, and an upper position of approximately between three and seven feet above street level
