I bought a back cali topper and then after fitting a roof book I very carefully cut out the a section of the top so that I could fit the topper whilst living the roof box in place. It works fine as 99% of the benefit of the cali topper is the way it keep rain and wind off the sides of the raised roof. it is very effective at doing this regardless of whether you have one that covers the top or one that has the the middle section cut out to allow a roof box. The only thing is that the older I get the lazier so I splurged a shedload of money on an isotop (stays in place on the inside of the roof space) and therefore don't use my cali topper anymore. If you (or anybody else) decide you want to get a cali topper and want one for less than half price then let me know, it in excellent conditions only used it on three trips before the laziness really set in. I am in East Hertfordshire
