I would like to do something similar, but to carry less than 100lb of lumber for very short distances. Can anyone comment on this product for this use (and a fair amount of rope / bungee)?

Proline CB5800 Roof Rack Railing Cross Bar Attachments. Car Roof Top Rack Cross rails and load bars.


Trying to see if we can get rid of our truck between the roof mount for occasional 8' - 10' stock and or a couple pieces of plywood and a trailer for the big trips. In either case I am never going to have to travel more than 2 miles or over 40 mph. Thanks in advance.
