Purchased a New '07 Commander (4.7L 4X4 Quad-drive II) last week. I will be using the 4X4 this weekend for the first time. I will be pulling my 4 wheeler on a very muddy road. All told, I have to pull the 4 wheeler about 20 miles round trip through the mud. My questions are 1) is it OK to use 4Lo while pulling a trailer? and 2) is 4Hi or 4Lo better on muddy roads? There are no hills or rocks to climb, it’s just a matter of keeping the car moving and on the road. Any advice would be appreciated.
