You have to deal with the driveshaft and different suspensions for trucks compared to smaller and more economical vehicles. I know there have been lots of threads on undertrays, but any help finding the best ones with pictures for RWD trucks appreciated.

Also: Undertray vs "skirts". You see the 18-wheel big rigs on the road with skirts effectively covering the trailer undersides and the fuel tanks.

Are undertrays more effective than skirts?
