I appreciate the feedback and to my surprise, went to the dealership and they told e it was a mistake as they brought the truck in on a dealer trade and did not order the "commercial" spec themselves. Thought I was going to have a fight but for $1500, went from a 6600 km 2500 AT4 [ needed a windshield] up to a new 3500 AT4 with extras. I am glad there is a shortage of used trucks as this 2500 AT4 is headed south of the border. So, I would have taken a 2500 without the "commercial" spec but they had none available and the ride on the 3500 seems fine. Again, thank you for the feedback and will pay better attention to the vehicle spec information next time.
