Re: Smittybilt Defender Rack
Another option would be a Yakima Mega Warrior roof basket. (The Yakima Load Warrior is similar but smaller)
They are 48 " wide and nearly six feet with one extension. They can be made as long as you want buy adding additional extensions and requisite load bars. They can be found used on Craigslist for between $200 and $350, often with the extension included. Additional new 22" extensions are around $150 on Amazon. They are well made , robust and look pretty darn good. A mesh base can be added if needed to provide more of a flat surface.
They normally mount to Yakima or Thule cross bars, but with a little creativity could be mounted to any cross bar or strut.
