Music in the commercial
"I vow to get up as early as you. I vow to haul whatever you can fit in my bed. And tow whatever you hitch me to. I vow to never complain, never give up, and never say never. I vow to be the best Sierra ever."
Scenes of the Sierra trucks hauling and towing in different terrain, from construction sites to the country-side.
