well the flop was caused by that large stump behind the jeep , came over the little sand burm, in 2nd gear 4 low so maybe 10 mph and as soon as I got to the top of the berm I saw the log but it was to late to turn . The front tire drove right over it but it hit the rocker and rolled the stump up higher and it was to much for the rear suspension and slowly flopped over . Thankfully everybody was safe and all the gear is always very secure so nothing shifted , only damage was to the rocker where the stump hit and a dent in the drivers door .
