So had a problem with my 1993 Garland since I bought it 2 years ago, when braking the caravan seems to over run and and there’s a clunk and a thud. The same goes for when pulling away from stationary. I narrowed it down to a knackered damper. I tried to push the hitch in to test it but it wasn’t budging at all.
I took the A-Frame cover off but couldn’t find any reference to the damper part number which is apparently stamped on some caravan chassis. I found two plates one that was on the A-Frame
And one that was on the hitch.
I googled 48.24.571.002 and all I could find was an old ebay ad stating (Ref;275E) BPW Damper 02.3722.08.00.0 for BPW coupling 48.24.571.002 P92535 Genuine BPW Hitch Damper 02.3722.08.00.0 BPW coupling 48.24.571.002 P92535 and then hit a dead end.
However I had identified that the hitch/chassis was made by BPW. I dropped BPW an email and they told me that that I needed part 02.3722.07.00 the cheapest I could find this was £81.16 plus postage which was a little high for my liking so I decided to do some digging. After matching up lengths/operating weights etc I found that part number 87000709 for the Avonride/Knott chassis was a match, I found this for £41.96 plus postage which is half the cost of the BPW one from the same supplier.
Due to the bargain hunter I am I pursured my search on ebay and found item number 201166665608 described as KNOTT AVONRIDE TRAILER DAMPER 750-1300KG 576000 87000709 FITS IFOR WILLIAMS for £39.25 with free postage.
Surely I should have been happy? but wait a minute I don’t buy manufacturer parts for my cars unless I can’t avoid it so why should I for my caravan? after a bit more searching I found item number 201322048394 described as REPLACEMENT TRAILER DAMPER FOR KNOTT 87000709 750-1300kg KFG13 & IFOR WILLIAMS for £27.25 posted!
So for a bit of investigating and perserverance I managed to save £65!. I ordered today and will hopefully be fitting it at the weekend.,
So for reference the BPW damper is
545mm with damper
Body length 330mm
Rated upto 1300kg
There is also a Ifor Williams matching part number which is P00937
I hope this post saves someone some effort/money let me know if it has!
