I recently bought an extended E350 that will be a minimalist setup. I need some storage on the roof. I'd like to haul kayaks/paddleboards/cargo carriers. I'm tempted to buy a rack like this
http://www.toppermfg.com/products/van-racks/ since they can be had for $100 used on craigslist. It would be great to buy a proper rack, but right now we'd rather save some money so we can take the van south to get out of Wisconsin winter for a while. The racks have 6 mounting points, are galvanized, weigh 750 pounds, and are 5x12 with crossbars every 2 feet. I don't care for the galvanized look, but I could live with it. Is there a reason why I haven't seen anyone with a budget built van with one of these racks? Thanks
