The new Chevy Silverado has been spotted testing and there's even some shots of the interior. Looks like it will have an upgraded interior like the new Tahoe.
The Silverado needs a big upgrade in my opinion. If I were to go GM I'd pick the Sierra because of the MultiPro tailgate.If the next-generation Silverado is good enough, then I might take a serious look into it. GM's Super Cruise highway semi-self-driving suite will be included and is a feature I would use a lot. I spend a lot of time commuting to job sites.
