Thanks for the reply. I was a bit unsure of going for a swivel like yours due to the build quality but if you have had no problems then it might be the one to go for. Do you get any paperwork to state the fact it has been tested?
I did not but I bought mine from Cheshire Motor Caravans although it is the same as the one that is pictured. I'm so glad I fitted it made such a difference while I was travelling round France recently.
