I occasionally haul heavy hardwood lumber. My 2003 ody had the pre-installed roof runners and I bought after market rails that attached to the runners. Never had a problem. My new 2016 LX has nothing at the moment. First off I don't want to spend hundreds of dollars on this. So two thoughts. Buy the OEM runners and shop for the rails like I did years ago or and here is the big question. Could I put on strong rails right onto to van itself without the runners? Any and all suggestions are welcome. Thanks.
