Sounds like you are having a blast with your laser level. Can't blame you, they are pretty cool.
I don't think that it will be particularly useful for checking the position of the cab as it relates to the frame. The laser can show the cab to be perfectly level, but if the gaps between the frame and each of the 4 corners is not within specs, you will have front clip fitment issues.
Cab adjustment is best accomplished as per the Factory Shop Manual. The frame needs to be checked for straightness if it is in question.

Thanks but looking at the FAM I was under the impression that measurements were taken with respect to a zero line 10” below the frame. Assuming a straight frame (the replacement is straight) I would think the method described above (checking measurements v the FAM) is correct, no? Happy to be corrected if I have missed something. The measurements above do confirm what I see visually.
