I haven't even used my little pop-top caravan yet (purchased last year), but during storage on a neighbour's field (I won't bother you with the story behind that) the brake rod and handbrake were damaged during repositioning of my 'van by them.
Trying to work out best options for repair (as it cannot be towed presently with brake rod sticking into the ground) I decided to check out "caravan" forums for some possible advice.
There are many such forums, but I noted that the Practical Caravan forum seemed to be much more active than others: I registered.
This post is just to say, for any TAS members with caravans, that the PC forum members are, indeed, very active, helpful and friendly. I can only recommend PC forum membership for caravaners (is there such a word) if you are not already a member.
