An RV ramp door is hingedly connected near the vehicle floor for selective opening and closing by a user. A weather-resistant construction of a ramp door includes an inner foam body having an inner face and an outer face, a ramp door inner surface, a ramp door outer surface, a first layer of thermoplastic composite material disposed between the inner face of the foam body and the ramp door inner surface, and a second layer of thermoplastic composite material disposed between the outer face of the foam body and the ramp door outer surface. The ramp door inner surface may be a slip-resistant material, and the ramp door outer surface may be a fiberglass panel. The ramp door may include one or more weep holes for releasing any trapped liquid.
