Anyone know if water will come in the cab if it gets to the bottom of the doors

 

Yep. Depending on how good your door seals are dictates how long it takes to get in there. I'f you're doing deep water crossings on a regular basis pull out any carpeting. Hell my trail Ranger has a herculined floor and my doors only go on the truck when its cold out. I'd rather deal with water in that than in my F150. Last time it got water in it I had about 4".

 

one time i was mudding with a buddy and we went through a water hole that was a little deeper than we expected... and i had to climb out of the windows to get out of the truck...we didnt have any water damage anywhere
