Agree that makes more sense.You're right, logically the dimension that stays the same when folded must be the width, the one that increases must be the height and the one that reduces has to be the length it actually sticks out the back
Bikes will obscure the number plate on your van so yes you will need to get a number plate made up. Can't help with fixing - I'd guess, looking at the light board element of the rack, that it will be pre-drilled - alternatively use some good double sided sticky tape. Personally I'd just take my V5 and ID to Halfords and get them to make one up and then work it out later.Quick follow up, now having the 928 fitted on Friday, I wondered if anyone knows if I'll need a number plate on the back, if so, can I get a standard plate and have it clip on, or is the one Thule sell which you write on the best option?
