We've had two tow-bars fitted at a place near Armley Gyratory, on Stanningley Road. I'm afraid I don't know the name of the company (hubby sorted it all out), but the price was competative and both jobs were done very tidily.
If you don`t mind travelling to Shelf, you can get one fitted by EECO (they also make them).
I have the current model Passat estate, they did a first class job while I waited, were cheaper than anywhere else I could find, and whilst there is a cut in the bumper, you have to really grovel to see it.
I've just rung Towbar Services Wakefield LTD which I think is the one you were referring to Sparky but they couldn't give me a price there and then so I'll have to call back.
Re-assuring to know that the cut in the bumper isn't visible.
Price depends if you have double electrics fitted ie if you require to run 12v in the camper such as the fridge whilst being towed , this makes it more expensive?
Thanks very much for all your replies. It's at Towbar Services Wakefield as we speak. Just need to do the impossible and try and book a pitch for BH next week...!
