I took them off, very easy. The little "wind/mud" flap on the rear was a bit of pain to put back on properly but nothing too extreme, just an inconvenience. After driving hundreds of miles with them on I've noticed the inner part gets the dirtiest obviously and it's tough to clean (I have a white truck though) but they've held up well. One has a very tiny chip but that's after hundreds of miles in different terrains (gravel, dirt, pavement).
