I don't have any direct answers for the OP, but I DO have some thoughts on the subject with relation to these comments:
4WL is important to me. We had a freak snow last year that piled up 10" in about 3 hours. There was a black WK that did not have 4 wheel low but was more like an AWD/All time system. He couldn't go anywhere (about 4 inches of snow), and ended up sliding into a ditch. In order for the all time system to kick in, he had to be spinning already and couldn't get a bit of traction. I ended up pulling him out.
Maybe it was a fluke, but 4WD Low made my day a lot better that night.
Down in this corner of PA we USUALLY get a couple of blizzards per year.
Honestly, I can't imagine the snow in VA is any worse (Hurley), but maybe the OP is getting some lake effect stuff so it is more often?
For about 2 decades now I've owned predominantly AWD and/or 4WD vehicles, usually (but not always) with snow tires. Not because I NEEDED THEM (99% of the people around here drive cars with all seasons and that's it, but even then I've had friends with RWD cars and snow tires, or AWD and all seasons etc. who typically have no real problems).
And honestly, during that time I (or someone in the family, usually my wife, has had a FWD car too).
I've HAVE NEVER
, not even once
4Low because of snow.
Hell, I drove a Subaru Baja (with snow tires) over 100 miles in a blizzard a few years ago with OVER 1 foot of unplowed snow ON THE PA TURNPIKE (you don't even want to know about the 30 miles of backroads I had to take after I got off the tpke). But it made it no problems.
I found the proliferation of TPMS to be the straw that broke the camel's back for me and I stopped buying snow tires with wheel packages for my cars. It's just no longer worth the effort for limited benefit.
As such I still like AWD because it helps to divide the load among the available traction and make up for the all-seasons.
SO unless you are driving in the peak of a blizzard, have tons of unplowed roads to travel, or need to cross an entire field of ice you probably don't NEED
snow tires (as long as you're smart, know your limits, and realize you have no braking advantage without them). And I REALLY REALLY think you don't NEED
Now the SRT offers a couple of challenges - specifically LOTS of hp and HARDER/WIDER tires which means you would have to watch it. Keep traction control on etc.
Cold Case already gave the best answer - and I suspect it will really depend on how much and how aggressively you want to drive in the rough stuff. If you're careful I SUSPECT you'll generally be fine.
IF you can find winter tires and wheels that fit on the SRT, I suspect you'll be grinning like a Cheshire Cat.
