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....

If you have 4wd high, it's likely using clutches to engage only on slippage. Rule of thumb is just don't do it unless you have an auto option. Chain driven systems lock the front axle, and even rear. When you turn the wheels spin at the same speed, when your inner tire does a circle the outer tire travels a longer distance, it takes more turning to do the same distance , so it needs a different speed, or, it needs to slip on top of the concrete to match the inner tire. If the road is not wet it can't slip, so it will to chirp chirp chirp. It will feel bumpy. Extreme turning can cause sliding , and as other have said, break a gear , or worse , the drive shaft itself. If you're truly interested , watch some YouTube videos.
