I have a new dually that pulls to the lift when in the left lane. It does not pull in the right lane. I have had it aligned by two companies and it's well within specs. The dealer said it's following the crown of the road. The SAI Included angel is off 3 degrees from left to right with the low of 16 on the left and high of 19 on the right. Any thoughts why my truck pulls to the left hard when in the left lane?

Thank you

Had a 17,18,19 srw 350 all were good my 2020 if left lane would hit the ditch on 7-8 seconds if I let the wheel go, same thing took in for alignment did not improve must be something with castor?? I run about 3-4 psi less in right tires helps a bit.
