Hi, I’m gonna buy a used 2016 Silverado LTZ 2500HD tomorrow. It’s from a Chevy dealer. It’s extremely clean. It has 76K miles. I’ve never had a diesel before. I live in the Boston area but also have a home in Rangley Maine. I snowmobile a lot. My 2016 Silverado High Country didn’t like to pull a trailer loaded up with sleds through the mountains. Is there anything I should know when I test drive the truck tomorrow? Any tips or tricks from the experienced guys on here ? Thanks in advance.
