Drove down to Somerset last month to pick this up for my Avon SR4.0 (and still saved approx £400+). With wide wheels (perfect for the sand/seaweed/shingle beach I usually launch from), roller coaster & spare wheel was only £745.
Chums with much more experience than me have been pretty well impressed by it.
Me? With rheumatics in both hands, it's made using my Avon much, much easier and so get to hop the waves much more often.
Nearly forgot - bought it from Paul at www.oceantrail.co.uk
