Drove ELMO from reno, ks to wyandotte, ok last weekend with the new seats. about a 4-ish hour drive. 196 miles. Seats mounted on springer bases were quite comfortable. no sore butt or back when i got there or home, and off road with the springer bases they were still comfortable. We were hauling people from the playing field (oklahoma d-day paint ball event) to the camp gound back and forth all day long. lots of bumping around, taking small detours (and breaking a few bows off the top(and didnt even knock anyone out of the back!)). Was great fun for all. Hauled the trailer down empty and a a MUTT on it on the way back. Overall, I love these seats, they feel good and lok even better.
