The seals for the door are on the inside so any gravel road traveling (of which i do a lot) produces a lot of dirt and dust inside the door. So when you open your door your beautiful interior is accented by a large build up of dirt. You cannot take a pressure washer to it because you have to have the door open to get at it, so the only option is the slow and tedious process of wiping it off with a rag. Then by the time you make it down the road it is full of dirt again.
