BurbMan....first, Congratulations on choosing one of the finest tow vehicles for the RVer. But, and there’s always the “but”...... many Ram owners refer to the computer as the “Lie-O-Meter”! We keep a log of all fuel mileage (computer vs pen and paper), all maintenance, etc. If the computer is “ever” (very seldom) within 2mpg of the pen/paper number.....it’s an anomaly! And, in 140K + miles, has shown greater fuel mileage than pen/paper computed less than a dozen times. Many times off by 5 mpg or greater! In spite of that.....a great truck and tow vehicle! Congratulations......and to remain joyous, “never”, “never”, compute your mileage with pen and paper! :B memtb
