Towing - Stay in RWD or change to 4WD?
We just purchased our first camper this past Monday and we are making our maiden voyage tomorrow. Our tow vehicle is a 2013 Expedition EL and it has an option for 2WD, 4WD Auto, 4WD High, or 4WD low....

4WD high is usually limited to 40 to 45 max. Any faster can cause damage. Read your manual. It should tell you.
4WD low is going to rev up the engine a lot sooner.
Low range you will run to the rev limiter fairly quick.
