Hi all, I know this is a specific rather than general question, but having just had a play with the roof bars on my XTR (having found the extra long screws and upstands under the passenger seat) does anybody have experience of Roof Boxes attached to them. My first impression was that they don't seem very wide spaced, is there a recommended maximum size? given that it propably looks like some type of top heavy snail with a box in place :) having said that they appear to be very solid and up to the job. Halfords are doing a 250L box for <£100, any body got any opinions on this subject area. i.e. noise, fuel consumption, handling, security, make. thanks Potter
