I gave a power armor to Veronica and she refused to carry it and therefore to wear it. This is a strange behaviour for a BOS member...
More seriously, I wonder how works the companion carry weight capacity. I know that it is related to the player carry weight capacity, but I ignore whate is the fixed limit for companions. I do not think that charisma influences this ability.
For information, I use JSaywer Ultimate Edition and it strongly reduces the weight that the player can carry. So if I do not want to change JSUE features, do I need a perk to allow Veronica to wear a power armor?
