They've all done fine, all of my rams have had 3.92 gears but of more relevance here, also with the anti spin, and with either bfg ko2s or falken wildpeak at3s. No pictures of my 2011 in snow surprisingly but have some of my others:
Also got to experience that Southern and Texas winter storm last February, driving from upstate NY to College Station Tx and back, with every travel day atrocious except for our very last returning home (the shortest leg, from Cleveland back into NY). The worst day was also the longest from a mileage and time standpoint, 800 miles over 16 hours from College Station to Nashville, in either complete ice or blinding snow/ice for the entire day. Here's some pictures of my truck along the way during that fun trip:
The 21 that I have now has the same setup drivetrain wise as my first 3 rams so I expect that aspect to perform the same, my tires are slightly different in that they are the factory version of the falken wildpeaks, the at3wa instead of at3w that I've had in the past. They look a little less aggressive but we haven't really gotten any real amount of snow here yet to test them out, so far they have been good in wet situations otherwise.
Not really big into using 4x4 often in the snow unless it's completely necessary, but have found it adequate when needed.
