We have a custom rack from Aluminess for sale - purchased in 2014 and only used once. Designed for a Ford E350 Extended Passenger Van. We did not include the welded crossbars in the original build but opted instead to just add our own Yakima towers and crossbars to give us more flexibility on where we place them (bike trays vs. kayak carriers vs. boxes). Total weight of rack without our towers and trays is around 130 pounds. Also added closer slats to allow us to walk on top as needed. A great product from a great company and included a ladder with it as well - selling the rack and ladder together along with all hardware. Perfect for a bike company or anyone using E350's to carry equipment. Cost 2500 new and selling for 1000 OBO. Call Joe at Iconic Adventures at 970-367-6907 or reply to this posting for more pictures. Located in Steamboat Springs, CO and can meet in Denver if needed.
I'd like to jump in line for the rack. I'm local to Fort Collins CO, but currently out of the country for work till April 1st. I can figure out logistics, just keep me in the loop if possible: 970-214-5636 and/or ejwargo3@gmail.com.
I'll have to modify the rack to make it work for my application but this is a great start!
