MT55 is listed as only 18 ft truck but is actually 22 ft due to the driver entry being used for store merchanise as well. Rear store is 18' while the front driver entry is the extra 4'.
Total truck length from nose to tail is approximately 28 ft. not including the lift.
Oil changed with only premium Valvoline full synthetic and K&N filter. Trip2 shows mileage since most recent oil change.
Only mx was due to Freightliner over-filling rear diff and not tightening the rear axle seal on rear passenger side wheels. Had to replace gasket and retorque bolts (Freightliner left only finger tight).
