We have a 2016 4wd/awd Sprinter that we have spent a lot of time exploring southern Utah, and surrounding areas. The 4wd is nice as we ski a lot too, but we have utilized the full range of ground clearance over and over again.
As for power it is interesting what people NEED now for power. It is absolutely plenty. Is it a lot, no, but I can cruise through southern Utah at 80. Some of the power issues come from people doing these amazingly heavy builds, with big racks and side ladders and then wondering why their van doesn’t stop, go, turn or get decent mpg anymore.
It would be great to not have to deal with Mercedes anymore. We have had to fight the service department to get things covered by the Mercedes extended warranty we purchased. They have done all of it but only after many phone calls. Ours has not been problematic and we have just over 100,000 miles on it.
I would to love buy a Ford next, just so service was more available. I will do more of my own service once our warranty is up. If Ford gets the same or close ground clearance I think I would give one a try.
As for the dual range transfer case, I read a comparison somewhere that said the low gear on the new Sprinter 10 spd box is actually lower than the low gear in low range on the older Sprinters. Not sure if this is the same for the Ford but worth looking into. I do like our low range.
We don’t do any rock crawling but do get pretty remote. Our Sprinter has served us well. I wish Ford would look a little more at some of the wishes of their potential customers but then again I don’t think the majority of the vans get used quite like ours. Would love to try a Ford.
