I tow a 5000 lb. snowmobile trailer to Michigan and back. The trip is roughly 1100 miles round trip and I use between 15 and 20 gallons. What could the problem be? Sometimes the 500 mile warning will come on when I still have a half tank of fuel left and I fill them up at the same time. If this is normal then I need a bigger def tank or a bigger bed to haul fluid in . lol I am not a happy camper by any means. Goes to the dealer again tomorrow. However they really have no insight into this issue!
