can anyone suggest a well made reliable fixed motor mover please for my Burstner 520tl. its plated to 1500kg.I know its generaly down to personal preferance but we had a carver unit fitted for approx 5 years and its been a load of 4xxx.we have had to put up with the caravan going round in circles and kangaroo hopping for most of its life.Harringtons of chester have been very good and doing there best to repair it by changing box, wires ,rollers ,etc but after one or two trips it plays up again. some have suggested powertouch movers, any expressed experiance with this mover or any other would be appreciated
