Picked up a 2020 Silverado HD Duramax High Country 2 days ago. Ordered GM floor mats (Rewards Points), BD Trim chrome tailgate letters, and Rough County Tri-Fold tonneau cover today. Cant wait to start making it mine.
Had same issue with my 2014, cleaned connections and used dielectric grease, still failed periodically. Dealer said there was a TSB pointing to brake fluid level, so they filled it to the brim. So far that seemed to fix the problem, but only pulled a few times since, then winter checked in.
I need the capability to have access to the bed. I liked the roll-up style but didn't like the side rails.The vinyl Tri fold fit my needs best, I chose the TruXmart for their price and quality (Wanted a hard cover trifold, but cant' find an excuse for the wife that I need to spend even more money on a truck that cost more than my first house).
