Al-Ko Shocks - and more to come
OK guys, particularly Biggirafe, Bigboack, Maingate Tony, Solent View et al - please accept that I have a sense of humour, sometimes sardonic but never malicious, which I am actually maintaining

as I wade through this mine field. There are two distinct sets of Al-Ko shocks - The Octagon Series 601204-7. The 204 green is up to 900kg single axle, 205 blue 900-1300 and red 1300-1800 and are for caravans and trailers as stated on the Al-Ko.co.uk website under shock absorbers.
Oddly, the Black mentioned by Bigboack and shown on the
Busy Outdoors.Com - articles and reviews for the great outdoors web site is no longer shown by Al-Ko on their site.

I have written to the Live assistant on this site asking for clarification and dimensions (including the all important 13mm internal bush size) as at first sight they would appear suitable as their stated rating is shown as up 1800-4000kg.
However on Al-Ko's site under Vehicle Technology > Automotive > Axle Technology > Shock Absorbers you will find motorhomes shocks - a black one and a blue one but they they don't show the ratings!!

However Technical support at Al-Ko have told me, from my VIN, that the AMC range 282251,2, 3 are for Motorhomes and that I need the Blue, 282251. I will be speaking to them again on Monday to clarify the situation re 601207 and where on their web site can I find the mysterious AMC series.
There are those that say that me being described as a cross between a Terrier and a Rotweiller is not a million miles from the truth

- it's not over yet and I will, as they say, keep you posted
