My wife and I were in Yellowstone this past August, our TT (27RLWS) is
31-1/2' OAL, and then add the F250 to that, we were fine, tight, but fine. We stayed at Fishing Bridge 4 nights, then moved on to West Yellowstone, as planned, which is about 40 minutes west, and stayed at Grizzly RV for 7 nights. Wow, what a difference! First off, we were glad to get out of all the constant noise and traffic, and move on! We wish we had booked our entire stay at Grizzly, the place is amazing, clean, QUIET, and plenty off room! Have fun!!!
