Playing around in my dad's 2013 200 series in hard packed snow. Not an expert on these trucks, I have a 100. Turning on crawl, in various terrain settings, it pretty much freaked out and sounded like it was ripping up mechanical parts. What gives? My dad told me he also tried the crawl in snow and experienced the same grinding/lurching unpleasantness. Searched here and didn't find a thread on this, but apologies if this has already been discussed.
