With all the crap I load into the bus for a typical trip, the bikes are not even noticed.I have gone with this rack. Though, not cheap.

> Hi folks
> 
> I want to transport up to 4 bikes on my '91 Westy. Should I go with a rack that holds four on the back? Should I put a couple of bikes on the front and a couple on the back to balance the load? What's best practice for bike racks?
