Have you observed these so called measurements? The truck probably will test out OK on an alignment rack. It needs to be set up in a frame machine used to pull frames. Looks high enough that you and a friend can pull a tape criss cross at several points with a hopefully equal measurement occurring correspondingly. If you find an unequal measurement try and understand why. You don't want to be made a fool when you present your suspicions.

Use this information to satisfy yourself or force the shop to confirm one or the other. Knowledge is power.
