thanks all .. i found some little nylon wheels today similar to razzmans pic and got 2 of them for $10 .. got to the shop tonight but the guy reckons he can make some out of some nylon tube thing he has and they will slip up under the trialer and be out of sight .. will let you all know how i get on and add pics once done
I dont want anything other than nylon otherwise it will possibly mark the coloured concrete driveway, its the only time that it ever hits so the nylon should still last a while, Cannot adjust towball height as it is in a fixed position
