Newby to this forum but elderly with respect to just about everything else. In all the above posts, there is no mention of the Tobacco Roots which without doubt, have some of the best wheeling in the SW part of the state.
Here are a few:
South Meadow Creek, FS 1221. McAllister access. My stock JK has no problems with it, but a couple of spots you need to pick the line well.
Some pics of S. Meadow from last weekend here: SW Montana weekend trip
North Meadow Creek, FS 965/6338/6340. McAllister access or take Warm Springs Creek road over the Revenue Flats from Norris. You might get a stock JK/TJ up these but highly likely they will not look too good after the run. Lots of boulders and I'm going to say lockers and/or winch necessary but rewards are some great scenery. I use my 3B flatty on these. Actually, there are quite a few miles of easy Jeep road just on the Revenue Flates off of Madison County Road 98.
N. Meadow to S. Willow Creek, FS160, McAllister access. Only a couple miles of real Jeep trail-very steep and can get pretty muddy, but no body damage.
South Boulder Creek, FS 107. Cardwell access. About 4 miles good Jeep trail to Sailor Lake trail head (1/4 mile hike to lake-Trail 7140, another 1/4 mile hike to Globe Lake, and maybe 1.5 mile hike (Trail 7167) to Brannan Lakes. If you do hike this area, keep the eyes open as we ran into a sow grizzly with 2 cubs a couple weeks back. She had a funny little red dot on her for a few seconds and was WAY to close.
Wisconsin Creek/Noble Fork, FS 6370/8300/6015. Sheridan access. Another very scenic area with several lakes, including Crystal, Jackson, Sunrise, Noble, and Blossom. The only one you can directly drive to is Noble. Stock Jeep can probably make all but some of the Noble Fork trail.
Bear Gulch/Boulder Lakes, FS 1007. Twin Bridges access. Cake walk into lower Boulder Lake but trail from Lower to Upper Boulder Lake has a couple shelfs where you will want lockers on both ends or you will be running line.
Indian Creek, FS 158. Sheridan access. Not too challanging but again, nice scenery. Used to be able to drive into Rossiter Lake but FS rebuilt the last 3 to 4 miles of trail for hiking only.
Pony/Windy Pass/N. Willow/Cataract Creek. Bunch of old mining roads in this area. Not sure what is now open as the fire last summer no doubt burned a lot of it.
If I get my 3B back together (scattered all over the garage for a cam change and a few other modifications), we are going to try to hit N. Meadow one more time in the next couple of weeks. If we do, we will likely camp overnight at Upper Twin Lake and do some hiking/fishing.
