We have an Alko 1221695 Jockey wheel fitted to our Bailey Pageant Monarch 2006 Mod. In under 2 years we have been through 2 new Wheels and end of season last year a new complete unit. Guess what first time out this year at Easter the wheel has buckled again !This is on an ordinary grass surface.I am starting to think "it is not fit for purpose". Any one any help, advice or comment HELP ?
