I'm looking at adding a Yakima rack system to my '07 Expy El to I can carry some bikes on my roof while I have my travel trailer in tow (so I can't use a hitch mount carrier). There's lots of used Yakima racks and brackets on Craigslist & EBay, but they're often older models so there's no info at the Yakima.com website. I'd like to know if anybody is using a Yakima rack system and what clamps work for the factory roof rail. Yakima.com recommends the LoRider Max clamp +CLAW 1 @ $170, plus bars, plus bike holders.
BTW, I started this search because I have to replace a single factory roof rack cross bar because my wife drove our cargo box into our garage and busted one both brackets on the front cross bar (thankfully nothing esle).
If anybody has factory roof rack cross bars they'd like to sell, PM me.
