This truck was in pristine condition, exactly what I was after in a vehicle. I passed on it because the asking price was pretty much what it was worth new in 2015. I have a hard time paying that kind of money for a 11 year old truck.

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!
