I think you need to go to
www.icbc.com and see what the requirements are for titling, insurance and registration. You would need to prove ownership before you even think of restoration or spending money. To be safe, I would edit-out the serial & engine number on the photo that shows the VIN tag. Big truck parts are very hard to find sometimes and among owners, there can be a sharing of resources and parts towards mutual benefit. Salvage if possible. Avoid modification that cannot be reversed.
Most likely the truck has had major problems and was parked. Parts have been removed from the engine, exposing it to the weather, so there may be rust internally. There are parts and emblems removed from the body. Restoration would be difficult. Labor costs are high.
Use as a farm truck is a possibility. Anything goes. If you are gifted mechanically you can find most anything running, most likely wrecked and swap over parts to make your truck a runner. Function over appearance.
You can also reposition the truck, jack it up and put on blocks. Add a sign saying welcome to our home. It would make a nice flower garden.
