Wondering what people can tell me about torsion suspension? I'm looking to build a small boat trailer (3m dinghy). The idea is that it can either be used as a day to day boat trailer when we're home or be dismantled when the dinghy is used in roof rack mode and we're travelling. I've considered the various fold-aways but have decided not to go down that route as I don't think they'd last as a day to day trailer. Long trips would kill them. The design priority (light, quick assembly) is wrong for us.
Anyway, I'm looking hard at rubber suspension ( like this; http://www.trailerwarehouse.com.au/contents/en-us/d30.html ) as it seems to make sense for a light weight trailer that's intended to be dismantled. No axle for one thing. My problem is that I'm getting wildly conflicting opinions on this sort of suspension. On the one hand I'm being told that salt water will destroy the rubber whilst others say it's a great system. Everyone has an opinion!
Anyone been down this path and have some actual experience of the product?
