Looking Back at a Year With a 2017 GMC Sierra 3500

 

By Matthew Barnes

We've had a 2017 GMC Sierra 3500 SLT 4x4 crew-cab long-bed for a year now, and we've driven it a little more than 16,000 miles. During that time, we have towed nearly 14,000 miles — mostly in the mountains at elevations ranging from 4,600 feet to 10,000 feet — with loads varying from 10,000 pounds to the truck's rated maximum of 17,000 pounds.
