For those interested, here are some links to the S280 shelter that give specifications.

You might also be interested in their ancillary equipment page. From any of their links above go to PRODUCTS at the top of their page then scroll down to Ancillary Equipment. They have all kinds of racks for the Humvee but I thought it might offer some ideas for other vehicles as well. Some of the racks don't look like they'd be too tough to make.
