Steer axle

5th wheel is all the way back. You are correct on fuel tanks they are under the sleeper portion of the truck. The tanker I pull is never 200 % full. Best I can do on it is 9200 gross gallons as it's a 9500 gallon tank. I'd say 50% of the time it's loaded to 9100-9200 gallons and the rest of the time it's in the 7000 gallon range. I'll be trying the Michelin tires out to see if that makes a difference .
