I'm thinking of treating myself to one of these: http://www.red9design.com/type2.htm and wondered if anyone had any experience of the setup?
Speak to dogs n dubs... he's got one on his van... I'm currently working on my own design for my van, but it will be a lot more expensive than that one, but it will be 3 times better!!
I quite fancy the idea of one of these too, also need to look into the insurance aspects of doing this modification.
