1. A travel trailer comprising an interior, a floor of the interior that is designed to support standing and walking persons, a vehicle frame, a front battery, and a rear battery, wherein:
the floor of the interior lies on the vehicle frame;
the vehicle frame comprises a coupling head, wheels, an axle, longitudinal beams, inner beams, and transverse beams;
the longitudinal beams lie on the outside of the vehicle frame;
the inner beams are arranged between and are spaced from the longitudinal beams;
two of the transverse beams connect ends of the longitudinal beams to ends of the inner beams to form an inner frame; and
the front battery, the rear battery, and the axle are arranged along a common plane within the inner beams of the inner frame, on opposite sides of the axle, such that a spacing between the longitudinal beams that lie on the outside of the vehicle frame and the inner beams of the inner frame protects the front battery and the rear battery from damage.
