When I contacted Vee Dub to say that several of the the rails were not the right size for the windows I was told that that is the size of the rails in the warehouse. They were around an inch short, and one was a further 5mm shorter. There was no offer of replacements. The tailgate window bottom rail had to be bent around the wiper motor. This makes the curtain difficult to close. The rail ends have to be bent also to fit the caps in, marking them. Why not make caps that fit?? All in all for the price tag of around £250 I was disappointed in the thought that has gone into them. For that price they should be better. So to should the customer service.
