AI Summary · 5 reviews

"Overall, owners appreciate the 2020 GMC Sierra 3500HD for its impressive performance, particularly when pulling heavy loads, and they find it comfortable and well-built. Many favor its strong track record compared to competitors like Ford and Ram. However, some owners are disappointed that it lacks features like a CD player and express a desire for better lumbar support adjustments."

Besides the bells and whistles we grabbed this dually because we pull a toy hauler. We went from a sturdy 2500 Dodge Ram to this beauty. We choose the dually 3500 due to the pulling capacity and payload as toy haulers are heavier in front to compensate for the weight that you can put in the back. We have no issues pulling it now and the truck does not squat because the support of the 4 tires. Other friends have regular 3500 and still have issues with the payload and had to put in more money into their vehicle to beef up the suspension when pulling a toy hauler because the payload is less. YOU WONT REGRET BUYING ONE!
