by hydrophobic and or oleophobic material in the interior of the body the embodiment enhances the ability of the body 31 to shed debris and maximizes the body 39 s potential to approach 100 of its achievable payload without the addition of hydrophobic and or oleophobic material to the interior of the body 31 in fig1 could be expected to build up debris 47 on the canopy 26 of the body 11 and on the inside of the body at the junctions of the front wall 57 floor 29 and side walls 17 the build up at the junctions is shown as debris 59 in fig1 fig1 illustrates the truck body 11 of fig1 with some structure removed to better show the load containment plates 61 i e the plates that actually contact the load of the truck body 11 to reduce or eliminate the buildup of the debris 47 and 59 in fig1 some of the plates 61 can be supplied as hydrophobic treated plates hydrophobic coated plates or they can be a base to which hydrophobic clad plates are attached and or oleophobic type coatings materials applied an example of an hydrophobic plate of sufficient hardness for the interior spaces of the body 11 is a crodon u00ae wear plate manufactured chromium corporation 14643 dallas parkway dallas tex 75254 united states of america fig1 illustrates the another example of an embodiment of the interior of the truck body 31 that offers the option of selectively placing on individual truck body planes 63 hydrophobic treated plates hydrophobic coated plates or hydrophobic clad plates applied to the inside of the off highway truck body 31 of fig3 in the body 31 of fig3 treated plates are placed only in the corners formed by the junctions of the body.
