Does anyone know if these ground the tail as easily as the 780? We have a 780 on which I bent the rear chassis member coming of the ferry at Dover, then I had air suspension fitted - no more problems I am now looking at changing to a 786 (pre 2007). The chassis arrangement is different and grounding may not be such a problem. I would welcome other owners experience and whether I need to consider air suspension again before venturing to Dover and beyond. Also are there any other pitfalls I need to lookout for with the 786.
