If you had to design one for your truck what would your ideal lumber rack be? First would you use round or rectangular tubing? I've seen one made out of stainless steel and another made of copper (both with large 3-4" tubing) and it looked too good for lumber but I'm not set up to weld stainless or copper. The copper was just for show its really too soft for a working truck. Has to be a full rack to take 20' long lumber. Has lots of tie downs, the new trucks went cheap with tie downs - four on mine new truck instead of eight on my old one. Provision for folk lift loading, and removable top bar above the tailgate to get it out of the way for loading something like a tall bookcase. Steel mesh across the back window, don't want anything like lumber or a RAS going through the passenger compartment. Clamp down instead of bolt down so no damage with holes drilled to the truck bed for mounting the rack. A 12V DC electric winch attached to the reinforced lumber rack frame would be nice to pull heavy stuff up to the bed.
Anything else?
