bike rack options for a TT / TV

Camping world is now selling the Bike Bunk (over the tanks) for $250 but you have to supply your own hitch mount type bike rack. If you already have a hitch mount, this is perhaps a good solution. But if you don't already have a hitch mount, then adding the price of a good quality bike rack would put total $ outlay in the neighborhood of the Arvika, which is a much better system, in my opinion.
