Looks pretty good to me as someone that grew up in Ontario.
You can have the undercarriage dry ice blasted or have someone go through with a wire wheel and paint. Fluid Film or Woolwax application after that's done. Original coating should last you a while in the Pacific NW.
As others have said I would check the KDSS valve on the driver's side of the truck because significant corrosion can seize those bolts and then you are in for a major PITA if you ever want to do a lift or any suspension work.
Check to make sure that the spare tire mechanism also works and isn't seized from corrosion.
These trucks really like to rust in my (very limited) experience. My rig has lived it's whole life in South Florida and has rust on the welds in many spots. The hitch receiver was also quite rusty. Good not to get too obsessed with rust when you own one of these (trying to take my own advice).
Good luck!
