Towing up steep gravel hill
So I live in a rural area and my driveway is about 400' of steep gravel driveway. I have a x213 that I figure is close to 6,000lbs loaded and towing with a 2013 Expedition with the heavy tow package.
My question is this: To get up the hill, do I use 4x4 High and a little speed or 4x4 low and crawl up the hill? Never used 4x4 Low for anything before but wanted to ask the experts here. And yes I read the manual and no it doesn't make any suggestions on what I should be doing in this situation
Thanks for your advice!
