I ve got quite a heavy German Built caravan that my Superb Wagon 2.0 CRD 170  Pulls really well,  However the loading on the rear springs produces an Angle ( V ) Which looks quite bad and occasionally bottoms out the Caravan jockey wheel over speed humps e.t.c.   The rear springs aren't bottomed out and theres no wheel rub , it just looks a bit off when towing.     Has anyone fitted Spring Assisters?  There like round rubber coils which wind into the the rear springs and stop
