I find the RRS suspension just a bit soft when towing (2200kg van) and wondered if changing the mode to dynamic would help but more important, would it tend to increase any wear or promote damge please?

That's exactly what I've found with mine, I set mine to dynamic and get a much better ride. Also put mine in sport mode, it holds on to the gears longer

Thanks - do you think it might reduce the life of the shocks. Thinking out loud, I don't suppose the 100kg noseweight is much different to the mother in law and I love frightening her in dynamic mode!
