Sometimes if the engine wasn't properly maintained, piston rings can get stuck and cause more oil burning.
Be sure to check you PCV valve and hoses, and I only recommend a real MOPAR PCV valve.
You can check the PCV valve but burning a little oil going over the mountains can/is normal. If going 75mph at 4000rmp up a grade of 6 plus for several miles with a full load.... yeah, lost oil.
