Re: Good Roof Rack Plans?
I'm in the process of making mine and am using 1"x2"x.0625" tube steel and 1x4 wood. I have 1 steel cross piece at every rib, supported by two legs about 1.5' in from the ends attaching to the top of the bus. Still figuring out exactly how to attach the legs (see other post), and I might run a length of steel down the ends, to cap the holes, and add extra rigidity. I will then have the 1x4s spaced 1" apart running lengthwise down the bus, connecting the steel substructure. I wasn't sure if 1x4 would be thick enough, but I bought a test piece, placed it on top of a couple supports at 2.5', and jumped up and down on it and it feels surprisingly stiff. I barely get any deflection. I opted for real wood over the plastic decking stuff, because it's quite a bit lighter, and doesn't sag. I'll post pictures when it's all done.
Edit: Steel was $160 new, and was enough for 10 cross braces. I haven't bought the wood yet, but I'm guessing about $100 to $150 for that.
