Depends on the year and model. On the T2000 and the T700, they're located behind the glove compartment. Most other models will have at least one fuse panel behind the kick panel on the driver's side, while more recent, multiplexed trucks will have a fuse panel for the chassis nodes under the hood on the driver's side. The T680 has an additional fuse panel for the sleeper berth located at the front wall of the LH side box.

Depends on year and model. Normally, there's a fuse and relay box behind the kick panel on the driver's side. On more current production models, the fuse panel for the chassis nodes and such will be under the hood on the left side of the vehicle. On the T680, there's an additional fuse panel for the sleeper components, and that can be located through the left side sidebox.
All fuses are under the hood.
The fuses are under the hood next to the battery.
