9. The sidewall assembly of claim 8 , wherein outer post includes

an opening configured to be exposed to the interior of the trailer through the at least one hole of the inner logistics post.

10. The sidewall assembly of claim 1 , wherein the outer post includes

a pair of protruding tabs, each tab formed at each end of a bottom surface of the outer post,

wherein the pair of protruding tabs forms a depression at the bottom surface to receive the inner logistics post.

11. A wall assembly for a trailer, comprising:

a side post including an outer post formed with aluminum and an inner logistics post formed with steel, the side post having first and second sides;

a first composite sandwich panel coupled to the first side of the side post, the first composite sandwich panel including a first plastic core and a first pair of metallic outer layers coupled to the first plastic core; and

a second composite sandwich panel coupled to the second side of the side post, the second composite sandwich panel including a second plastic core and a second pair of metallic outer layers coupled to the second plastic core,

wherein the outer post includes a pocket configured to receive the inner logistics post, the inner logistics post configured as a straight slab so that the inner logistics post stays inside the pocket without any protrusions out of the pocket,

wherein one of the first pair of metallic outer layers and one of the second pair of metallic outer layers are configured to extend over the pocket of the outer post and to face the interior of the trailer.

12. The wall assembly of claim 11 , wherein the inner logistics post includes

at least one hole formed within a gap between the first and second composite sandwich panels, the at least one hole configured to be exposed to an interior of the trailer.
