Not sure if you've already made the trip but I've driven to trailheads on both sides of Dolly Sods in the GTI and never had an issue.
Its mostly gravel roads but there are the occasional pot holes, rocks etc. Just keep a reasonable speed and pay attention and you'll be fine. The only issue I ran into was parking on the side of the road (it was crowded and this was overflow) there were some places I knew ground clearance would be an issue and had to keep searching.
Have fun, it's a beautiful place to explore!
