It was a 2017 chevy 2500. Ive never drove a van before and it felt like it was swerving a little on the highway. Is this normal? Im assuming its because its a big box and not very aerodynamic. I usually drive a f250 and it does it too but its an older model. I also smelled some burning which im assuming is new paint. Ive never bought or driven a brand new vehicle so this is all new to me.
