Nothing fancy, just a nice and sturdy steel rack. The side rails are 1.32" x 0.133" A500 pipe size tube with 1" x 0.095" HREW tube cross rails. I'm going to add another front and rear cross tube with the 1.33" stuff that has bends in it for maximum space. I decided to make it a flat top to keep it low and also so I can still haul plywood up there. I have been really pushing my luck with the factory side rails and homemade crossbars. The last and probably sketchiest thing I hauled up there were the pieces of 21' tube. The distance wasn't far and all slow back roads but it still made me nervous.
Building this is a lot easier than I thought. All I planned on doing was bending side rails and I ended up with this:
Most of the rack
It weighs about 50lbs hopefully it doesn't affect handling too much. Looks like the weak point will be the studs coming out of the roof. There are 8 of them but they are only 6 mm. Haven't heard really anything about them breaking, but I wonder about them shearing in an impact or hard flex.[/quote]
