A tailgate for a pickup has an opening equal to about 70% of the area of the tailgate. Louvers in the opening direct air from the bed of the pickup downward. The louvers permit vision from the driver of the pickup to below the bed of the pickup behind the bed thereof. The louvers prohibit vision from behind the pickup into the bed. The louvers are held in slotted stanchions by a bolt within the hollow stanchions. Each louver may be independently replaced.
