Oh dear,your tow hitches are not the best looking accessory . I had one fitted today at Indespention,its a trailer & towing company. The towbar is a WITTER detachable, comes with two keys. The mounting bracket & electrical socket are completely hidden by the centre blanking plate,no cutting was required. Took the fitter 2hrs 40mins to fit & the warranty on the towbar is for the lifetime of the vehicle. I'll post some pictures in the morning.
