Did you fill the DEF tank all the way? Doesn't sound like it was full. I get DEF at Walmart in 2.5 gallon boxes for about $11.50. DEF tank is 5.5 gallons and usually lasts about 5,000 miles. Except under heavy towing mine might only last 3,000 miles.
Boy did you bend over at Wall mart? Generally at the truck stops DEF is $2.78 you paid $4.50!
Generally my Dmax asks for DEF about every 3500 miles that doesn't mean it is empty but you need to fill in the next 1000 miles.

Go where the big boys play not at a "stick it to um" store.
