We just finished a 5,500 mile, 4 month trip starting in Fort Worth, TX with travels to NM, AZ, So. CA, No. CA, NV, CO and back home. We drove the highs (Red Mountain and Monarch Passes in CO., 11,000+ feet) to the lows (Death Valley’s Badwater Basin, -282 feet) and in temps that varied from 48 degrees to 113 degrees and in all wind conditions.
Our MH is the Georgetown 378TS. We are full-timers and are fully loaded out. We tow a 4dr, 4WD Jeep Rubicon, four down. We run the generator while driving for A/C and computer purposes.
I try to stay at around 2,200 RPM and 62-65 MPH.
BOTTOM LINE MPG: 6.9 MPG
I feel the dash computer is as accurate as you can get over this many miles driven. Manual tracking calculations and filling your gas tank the same each time will only make a minuscule difference and is not worth the time.
