DEF Consumption

[Thook1943]

I’m pulling a 15000 lbs Grand Design Solitude with a 2021 RAM 3500. While towing I’m going through about 2 1/2 gallons of DEF in around 1000 miles. Does this sound about normal?

Very similar consumption on my EcoDiesel when towing near max GVWR. Seems to drink the stuff towing, but get almost 2.5 times the mileage on def when not towing.
