Just acquired a used Silverado Hybrid. The front air dam is missing, should I buy a replacement or build a larger-than-stock version?

It has instant and average MPG sensing, should I also get a scangage? I'll be doing a grille cover, is it helpful to also have temp sensing?

I'm going to make an aero bed topper customized to the work I'll be doing out of the truck, but I'd like to hear suggestions and input about favorable designs!
