If you drive in through the entrance of the Rogers camp staging area and head towards the Browns camp staging area on the west side, there is an easy trail called Browns Powerline (6). Towards the east, is Powerline (4) which is fairly easy with exception to a small section of Powerline (4c), which has a nice off camber root and small boulder slope. A stock Jeep would be able to make section (4c) during dry conditions; however, if it is wet and muddy - one may struggle and may require a tug or winch. There is a portion of Powerline where stock Jeeps should avoid – (4e) or Little Rubicon, one just needs to drive by to see why.
University Firepower (10), last I checked was closed – at least the 1st section of the trail. If open, there are some nice hill climbs/descents for a stock Jeep.
One of the longer and scenic trails, Cedar Tree (13) is a moderate trail but I’ve made it through when I was stock.
Hoodraiser (20) is also a nice trail for stock Jeeps and close by is Hogs Back (18). There are two sections to Hogs Back, a fun off camber hill climb and a longer section with extremely tight spots and turns. A stock Jeep is able to navigate through both sections although the off camber hill climb may be questionable, but I have seen stock Jeeps (including myself) make it
On the west side of TSF (exiting off mile marker 18) there are two moderate trails: Rogers road (36) and Firefox (41). I've personally run these trails while stock.
Finally, there is Archers Firebreak (28) which has various trail conditions ranging from easy to difficult. It’s a nice long trail and contains bypasses for stock vehicles for the difficult portions.
