It should be called 'filler' because that is all it is. The wall is the same thickness regardless.
agree with the term "filler" as it looks like in the pics as though it reinforces walls more horizontally and perpendicular to the outer veneer panel. A veneer applied to a solid piece of plywood extending floor to ceiling and perhaps replacing a lot of the internal sticks,staples, and glue would weigh more, but may not be an issue for the person wanting additional strength vertically and perhaps more rugged construction for a given wall. However its also possible that rigidity vertically floor to ceiling is not desirable in a bouncing trailer. Perhaps also the current stick,staples, veneer and glue wall construction is sufficiently rigid as a unit when all appliances, fiberglass bathroom liner, etc are installed in conjunction with the hollow walls.
