The only bad thing I can say is first thing to watch with a GN over a tag is they cut quicker. Meaning that if your close to a ditch or something on the side walk, turning the truck close to the curb will result in embarassment.
ops: Found this out the hard way with a 36' GN with a tractor on it. But now then besides my 20' tag car trailer wouldn't have anything but a GN
