<font size="4">I currently have van skirting on both side's of my van. My question is would it make sense to remove these? Are these providing some kind of aero-dynamic effect for better gas mileage or are the just dead weight?</font><div><font size="4">I'm not concerned about looks. I want what's gonna give me the best fuel mileage. I'm also concerned about going off road with the side rails being so low. The step is nice though getting in and out of the van.</font></div>
