43 is designed to have a slightly greater height and slightly greater width than acorresponding rib member 16 received by the ridge member 43, to provide ventilation space 45 between the ridge member 43 and the corresponding rib member 16, as best disclosed in Figures 2 and 3. If the bottom bed wall 15 is flat> then the ventilation space 45 is substantially greater.
This ventilation space 45 is essential for the elimination or minimization of condensation and moisture which otherwise might become trapped between closely-fitting~ complementary liner ridge members and truck bed rib members.
For the same reason, a ventilation space 46 is provided between the front liner wall 31 and the front bed wall 17, as best disclosed in Figure 3.
The tailgate liner 27 includes a central panel portion 48 having ~.l front face, a renr face, an elongated top portion, and an elongated bottom portion. Tlle elongated top portion merges into a top hook-shaped flange 49 hile the elongated bottom portion of the tailgate panel portion 48 merges :into a bottom hook-shaped flange 50O Both of the hook-shaped flanges 49 and !;0 project rearward from the central panel portion 48 and are adapted to ~xtend over or across and then slightly behind corresponding top and bottom edge surfaces 51 and 52, respectively, oE the tailgate 28, as best disclosed :in Figure 3O The hook-shaped flanges 49 and 50 are adapted to closely fit and receive the corresponding top and bottom s~lrfaces 51 cmd 52 of the tailgate 20, so that when one of the hook-shaped flanges 49 or 50 has been fitted over the corresponding surface 51 or 52, the remaining or other hook-shaped flange 50 or 49 is manually Eorced, with a moderate degree of pressure, over its corresponding engaging surface 52 or 51, ~mtil the other flange is snap-fastened over the corresponding surface, to firmly hold the tailgate liner 27 securely in plnce to complete:ly cover the interior surface of the rectangular-_ 5 _ .

~8~ g shaped ~ailgate 200 The bottom edge surface 52 of the tailgate 20 is substantially a circular or cylindrical surface having its center of curvature substantially coinciding with the pivotal a~is of the hinge 21, so that there will be a substantially close fit between the bottom surface 52 and the end surface 54 of the bottom wall 15 of the truck bed 12, regardless of the pivotal position of the tailgate 20. Thus, where the edge surface 52 is substantially circular, the corresponding hook-shaped flange 50 is also circular and extends through an arc of at least 90O The extent of the arc of circular hook-shaped flange S0 greater than 90 is only enough to permit the flange 50 to be snapped over the arcuate edge surface 52 with a moderate amount of manually applied pres- -sure, and yet firmly hold the tailgate liner 27 snugly upon the tailgate 20~ :
The extent of the curvature of the bottom hook-shaped flange 50 will of course tlOpOlld UpOIl the resilience of the central panel portion 48, which in turn ~cpends upon the elasticity of the plastic material, the wall thickness of the panel portion 48 and the rigidity of the central panel portion 48, which in turn depends upon its inherent reinforcing structureO
In a preferred form of the invention, the central panel portion 48 comprises a plurality of longitudinally spaced rib members 55 which extend transversely of the tailgate 20, or in other words are disposed vertically when the tailgate 20 is in an upright position, to improve the impact resis-tance of the tailgate liner 27 and to improve the strength and rigidity of the tailgate liner 270 The central panel portion 48 is also preferably provided with an enlar~ed, lower rib member 56, preferably intersecting with the transverse rib members 55, and preferably having coplanar interior surfacesO The lower rib member 56 is preferably located to oppose, in close ju~taposition, the renr edgQ of the bottom liner wall 30, to minimize the space between the , . ~ - : , - - , :- . : .: .

tailgate liner 27 and the bed body liner 26, to prevent small articles from leaking or falling from the truck bed 12, when the tailgate 20 is in closed position, as disclosed in Figure 4.
Moreover, the lower rib member 56 provides an elongated stop or buffer in the lower rear end of the body liner 26, where impact from objects within the truck bed 12 are most likely to occurO
The body liner 26 may be provided with slight drafts in the side walls 32 and 33 and the front wall 31, relative to the bottom wall 30, to permit nesting or stacking of a plurality of the body liners 26, in order to `:
economize space in storage or shipment of the body liners 26.
Furthermore, the plastic material from which the body liner 26 and :`
tailgate liner 27 are made, may have appropriate pigments or coloring material added in order to enhance the appearance of the liners 26 and 270 In the preferred form of the invention, the liners 26 and 27 are ~:rocrably vac~l~n--formed :~rom the ABS-LS ~Trademark) plastic sheet materialO
