Hi Willie. If you measure the distance between the rear panel and the cross piece between the rear chassis legs I may have one to fit your Motorhome It came off a Motorhome fitted with an alko chassis which I know your Motorhome has . This is a towbar made by Alko Kober to suit their chassis on a Hymer but may also fit yours with a slight alteration. It has a detachable ball and in good condition.
I will be in Cookstown on Friday evening next on Grandad duties I can bring it with me and try it on your Motorhome if you want.
Grandad can leave Grandma on her own for an hour or so with the children to check this out as you don,t live far from where I will be. lol
Willie.
