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.
I haven't seen a 4WD truck where 4-HI has a limited speed. I have ran both my old '96 F250 and my new F350 at 65+ MPH in 4-HI many times. The F250 was a manual transfer case with manual hubs, and I believe the manual said to slow to 55 to engage 4-HI, but it didn't mention anything about limited speed once it's in gear. My new truck is all electronic and will engage 4-HI at pretty much any speed. The only thing I do to help it along is back out of the throttle until I get notification it's engaged. I don't even think you have to do that though.
