Had another trailer towing trip and some more offroading, and some offroading with the trailer.
We found a sweet camp spot and decided to pull the trailer up a few days later to camp for a few days. The paved road up the canyon was narrow, steep, and winding. I got stuck behind an F150 towing a tractor and we were only going about 15-20 and that just was not enough speed to keep the transmission cool. It got warmer than I would have liked but not so warm I felt it was an issue. I really think we needed a little more speed to keep things cool. Once I hit the dirt roads I put it into 4L and the temps came down really quick and all was good temp wise for the rest of the tow. The roads ended up being a bit rougher than I remembered and the trailer wanted to drag here and there and I had to be careful not to rip the plumbing off. Never once felt like there was an issue with not enough power though, that was always great.
Coming back down the canyon was great too. Home for me is at about 4500ft and the camp spot was about 9300ft. We camped in the Heber Mountain area, the town of Heber is about 5600'. So, we went up 3700' in a relatively short distance and had to come back down that. On the dirt roads that were really steep I used the hill descent control and it maintained speed great and worked really well even with the trailer on. Very impressed with that and I even used it a bit on the paved roads on the steeper sections where the turns were tighter and I couldn't go faster than 20. Other wise, I kept it in tow/haul and it did well at maintaining speed with the occasional tap of the brakes to bring it down a little slower.
We went out on a few trails to let the kids play in some streams and ponds and I did find a few places where I rubbed the undercarriage a bit. My brother's chevy pickup rubbed too and it has a shorter wheelbase than the expedition. Only bigger tires and a lift would have helped.
Overall, I was very happy with the expedition and wouldn't hesitate to buy one again.
