Steve,
Best $400 I have spent in a while, took three guys 2 hours. I'd come and provide "Systems Engineering" services, but it looks like the Fall Cruise is coincidnet with your project and I had already made a commitment to go.
Do NOT attempt to unload the long rails from your truck without help, tho'. They are at least a 3 man lift. One has the hydraulic cylinder in it. The guys set the uprights and crossbars in place first, then lifted the rails from the truck directly onto the cross bars.
