Coming in late to this, but I always thought that the difference (other than a branding difference) was that a ladder tower had a fully useable ladder with a bucket on the end. A Tower Ladder only had the escape ladder that is only used in the rare case where you can't get the bucket lowered and the emergency hydraulics are not working. I am not even sure if this has ever happened.
As for the county only recognizing ladder and tower ladder, isn't that a bit like saying we will consider all engines as hose wagons, we don't care if they have pumps or not? A telesquirt is most definitely a type of engine but a snorkel is it's own thing with some unique features that might be nice to know about, instead of having to remember which number truck is a snorkel.
