I have a 97 Cherokee that has a 5" lift and 35" tires. I can do a slow water crossing headlight deep no problem, it won't even leak water into the inside despite the water being halway or more up the door. Now the keyword there is a SLOW water crossing, you can't go fast because the air filter is inches above the water at that point. However, if you come to a stop it immediately fills with water lol. Its amazing how such a slow crawl keeps it dry but its bubble bubble glug glug as soon as you stop.
