91 Dodge airocap

This is my prototype airocap
Attachment 17595
making my rain drop

Truck is a 91 Dodge D250. 2wd 3/4t
A less than150lbs for complete airocap and headache rack
I used 12mill boat shrink wrap for my prototype covering
http://pages.ebay.com/motors/link/?n...363918&alt=web

$169 usd shipped for 10 ft x40ft this thickness is only available 40ft wide by $10usd per ft.
Thinner, cheaper, narrower shrink wraps are available, other cover options are ortex600, ortex6000, aircraft fabric, or regular canvas as well many others. I went with shrink wrap for quick repeatable and smooth and cheep prototype. for the aircraft fabric and ortex they require special adhesive to attach. Ortex600 is my choice for my final covering and canvas would be flapy and heavy after waterproofing

the canapé can be removed for aquard load or simply closed on the load.switch leaves the headache rack with its taper from cab width to mid bed rail . The steel frame can support aprox. 180lbs (me) hanging in the center. Can you say snow load

I set the rear defuser at approximately 10" past to clear the tailgate for opening and closing without opening the cap
