I unhooked my F350 dualie from my camper and forgot to let the tailgate down. It tore my tailgate up!
Check out this fifth wheel tailgate that I found. It looks great, it is made for a fifth wheel camper, and it is louvered for gas mileage.

nice it actually helps fuel economy

 

they can be painted to match your truck… i liked the fact i could see through/between the louvers...
