I had to run at it 4 times before I could finally get up and over! I believe it ojnly died once, and that was my fault. Mostly 4 low just didn't get me the momentum to get up the dune. Once I ran at it in 4hi it was a different story.
thats cool, looks like you had alot of fun, can't wait to get the jeep back from the shop so i can go get it stuck some more, this time at least I will have the super nerfs
