About 2 years ago we went thru yellowstone from the north to the south with our truck and TT (24 ft) Had no issues with the roads and yes some of the pull outs will allow for both but most really dont. Get to your campground and drive the suburban around instead. Tetons are the best IMO as is Jackson. Home of the National Elk refuge has a great visitor center to boot (2-3 hours to tour walk around) and Jackson itself has some nice walk around areas. We stayed at the old KOA there I think its just a private now. They did offer rafting trips!
