Abstract
A vehicle extender includes a flexible flap supported by a metal extender for closing the gap between the cab and trailer or between trailers of a semi-trailer truck. The flap and extender are preferably coupled together to permit these components to expand and contract relative to one another so that the flap resists buckling. In one preferred approach, the flap is slidably coupled to the extender, although a fastener may be used to hold the flap in place. In a specific form, the extender and flap have mating edges which are configured to engage one another. In another embodiment, the flap is indirectly coupled to the extender by a support.
