Im due for an alignment and I can see adjusting the caster, toe, etc etc. But you cant adjust upper and lower control arm out or in, so I guess im lost on how an alignment would help the whole truck.

As you adjust the caster, it effects where the C/L of the spindle winds up (within limited reason). If the caster is way off D-side vs. P-side, it could have an impact. I don't know if it would be as noticeable as in the pics, but it's something to consider when trying to dial things in.
The body placement on the chassis is a common issue on older vehicles. Small to moderate collisions over the years can easily shift the body toward one side or if the impact was to a rear corner it could 'diamond' things (one corner forward, the other back).
If the truck was known to have been in minor collisions, it's a good idea to have the chassis validated as being square so you're not wasting time/money chasing a ghost. Make sure the alignment is good (needs to be done anyway, right?). If things are still 'off', start measuring reference points on the body to the chassis & compare side to side (take as many diagonal measurements as possible).
