Interesting posts from Larry ,Prof and Clive.
The question of Towbars and Modifications must be the most often raised issues on here over the years.
I have just renewed with a different motor insurer. My previous and now the new one specifically ask for details of any modifications that may have been carried out after construction of the evehicle . They then give a list of modifications the last one being
“ any other not listed”. Guess what Towbar features. No difference in the premium.
I can only speak about the VW Touareg and Westfalia.
The oem rear cross member is substantial . It stiffens the entire rear end, protects the fuel and Ad blue tanks from rear impacts and stiffens the effects of being T Boned on the rear N/s and O/s.
The Westfalia towbar beam is a direct replacement and certified by the powers that be , Europe with mine, that it is as good if not better than the oem. It is a massive full sectioned piece of steel very similar to the oem but with welded add ons too.
I understand VW will have been consulted and agreed the spec. I am therefore confident my safety has not been compromised.
However I expect Lutz and Roger will know a lot more than me!
