Access Cab rear profile

Has anyone drawn up the profile for the access cab as viewed from the rear? looking at bending pipe for a bed rack and would like to CAD it up.

Also does anyone know the weight limits for the mounting of a roof rack? I would like to have a rack that matches up with the height of the bed rack to allow for a large platform tent going across the bed and cab.

 

Your trucks roof can is strong enough to hold your entire truck, probably 3 times over. The only limit is your vehicles payload capacity and how well you mount the rack.

"A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor."
