I am having trouble finding the detailed definitions for the different asset type options when adding a vehicle (A-Automobile, S-SUV, T-Truck/Van). I was thinking there was a difference based on Gross Vehicle Weight, but can't find anything. Would there ever be an instance where I would add a vehicle as a N-New Personal, or U-Used Personal?  I am having trouble with some of our vehicles not fully depreciating in the system and wondering if I am using a wrong type, or what is happening.
