If you get a bow wave going great if not and you stop your done. Best to know how deep before you go in.
The water crossing process can very tricky so if you don't have to be the lead let someone else check it out.
It is also expensive to change fluids all the time because not all Jeeps have water tight gearboxes and differentials. All of which need to be changed or checked after a day of watercrossings.
I now live in the desert and have only had two water crossing which werte about 12-20 inches lucky me.
