New truck alignment question

Hi Everyone, just bought my first Taco, its a 2020 4x4 TRD OffRoad.
During the test drive, the truck pulled slightly to the right when on the highway. Sales guy said its not problem, sometimes happens from the train, they will align it.
Bought it, they aligned it, tracks perfect now. (I forgot to ask for the printout)

My ocd is kicking in, so I drove it on many types of roads, it does steer and track perfect. Then I started reading here seeing peoples alignment pictures. So I just had to crawl under mine and check out those little oval alignment washers to see what they did.
What I noticed:
- Passenger side: steering rod adjusted, the lower control arm oval washers were not touched, the center mark is just about pointing straight up on both and the factory blue painted lines are all there.
- Driver side: rear washer set just about all the way to the left of center (second mark from left end), the front washer is set to 3or4 marks to the left of center. I do not see any factory blue lines on the bolt, there is on the nut.
- I didnt see any type of adjustments that could be made on the rear axel, any place I should look?

Any thoughts if everything is fine? Can I put my ocd to rest?
Thanks!

 

No rear axle alignment adjustments for a solid axle with leaf springs.
