The RV ran out of fuel with 70 gallons of diesel fuel in the left tank...and we were only 40 miles away from home after traveling 2200 miles. Fortunately we ran out of fuel in the right tank on a beautiful night with cell coverage, but the shoulder was very narrow and the cars and trucks were blazing past us in excess of 75 miles an hour. Fortunately the hazard lights and triangles we placed behind the RV prevented us from being ran into. Taking the RV to the shop next week to be repaired, but just curious if anyone else has had this same problem. We love the RV, but running out of fuel with 70 gallons of fuel in the left tank was very unexpected. Looking forward to any advice or comments. Thanks.

Haven’t exierienced that but wondered about it It sounds like the fuel transfer from left tank isn’t happening as it should The computer gets level signals from sensors in each tank and controls the transfer pump and works to keep fuel level the same in both tanks In our 6400 as we go down the road we can watch the gage drop and then rise as the transfer happens then drop again then rise again It is a slow process but noticeable and works Suggest an International dealer should be able to diagnose and fix the concern
