I have a box trailer that i want to use as a basic offroad trailer, nothing hardcore, just to get the camping gear to a campsite. It currenttly has 14 inch rims on it, and i want to put the same rims as the cruiser under it, 16 inch 285's. the eaisest way to get extra height and clearence is a spring over. Has anyone done this , and how hard is it, and what do i have to watch out for. If this dosnt get me the required clearnce, i will put extended shackles on it and modify the mudguards.
