What are the high quality tanker companies in the Northwest USA?

Tank farms are probably gonna be near the big cities or the ports......Just the way fuel hauling works.

 

Look into hauling bulk cryogenics. Liquid Oxygen, Nitrogen, CO2. It’s probably the cleanest hazmat tanker work there is. The tanks are baffled Mostly daycab work. Layovers are in decent hotels. Very highly compensated. Your experience would be highly sought.

Praxair
Messer
Airgas
Air Products

Key in Cryogenics in the “Truckers Report” search line.
In my HUMBLE opinion it’s top tier “company” trucking

Find out who hauls out of the Sinclair refineries in Sinclair and Casper, WY - and although it's a little bit out of the area you mentioned, the Holly / Navajo refinery in Artesia, NM. I know that Groendyke has a terminal in Artesia, and so does Pilot Flying J.

You might also consider crude oil gathering in the Bakken or DJ basins.

 

On a lot of tanker jobs you might not see or talk to another living soul for days on end. One of our night fuel drivers comes to work after I go home and he's usually finished and off duty before I get back in the morning. I talk to him on the phone once in awhile. He gets his dispatch by phone from the customer.
I asked him last year to send in a picture of himself so none of us will forget what he looks like. He's been here over twenty years and you couldn't blast him off that tanker with dynamite.

 

Hausmann Motorsports in ND hauls bottles all around.

They run top of the line equipment.
