Make a removable air dam for the 9 to 11 months that aren't hunting season. That's what I did with my suburban, in the event of hunting season or deep now I have 3 bolts on each side that once removed release the air dam.
Go to highway tires and a set of snow chains. They will be the baddest mud tires you will ever use. No point in wearing out expensive, soft, quick to wear out muds with 99.9% highway miles. I used to buy aggressive mud tires back in the early 2000s, then switched to aggressive A/T tires for a little while then to highway tires and snow chains back in 2009.
The highway tires lasted 2 to 3x longer than the muds, were cheaper by a lot and rode better.

This year my friend put his set of muds on his truck for deer season, where he is the limit was 5. In an unusual chain of events he tagged out the first day. So I think he had his mud tires on for a total of 3 or 4 days. He has had the same mud tires since 2012 and they are still like new.

I have low rolling resistance tires on my Nissan leaf and it has snowed twice here so far for fall/winter 2019 and they did great. This "Winter" for west Texas and eastern new Mexico has been labeled as "extreme" by weather dot com.
