I have been surprised at how the hill climbs go, moon dust and ruts or snowy messed up track to a dead end log landing. that is with highway wranglers. it has been said the awd activation is hard to discern.
deactivating the stabilitrak is good prior to hitting the scariest climbs.
Wheelin' is often mostly tire placement and momentum mgmt.
I goose it when it looks like I am somewhere I'd get stuck or really high centered. Riding the ridges through puddles, ice puddles, the moon dust ruts etc.
