Found this company through the latest evo magazine. May be an easier setup for those of us who take frequent road trips with significant others whom like to take along the kitchen sink.

It's 79 + 25 for shipping in GBP, so probably around $150 in usd. They also have the traditional metal racks.

 

Ive been looking for something like this for a while now. Need to find a wheel and tire rack for the trunk haha.
