Thanks Rhys (and others) for the info.
Too far out yet for me to able to confirm leave from work, but jeepers it looks like a great trip to do.
Still a bit concerned about towing nearly 3 ton along the beach on a trailer with standard type 14" wheels though.
I can't get bigger wheels in under the guards so I might seriously look at puting together a removable lazy axle to make it tri-axle for beach work. Had a good look under the trailer and it would be quite easy to put a quick change axle on slippers in front or behind the current tandem.
