And one I forgot to ask...

[Dave (Kent)]

With regard to Sankey trailers - is it possible to use a standard pin-type tow bar, or is a Nato coupling required? (using std trailer bit!)

Thanks

I'd be inclined to stick with a NATO ring hitch; nice and strong. 50mm Ball are only rated up to 3.5 tonne I think. If you keep the ring hitch you can still use the trailer off road. I have used one green laning to carry half a tonne of stone for lane repairs, slow and steady they tow very well, even up quite tricky lanes.
