So just picked up an enclosed trailer. I remember seeing some people just drive their rzr into their enclosed trailer put it in park and close up the doors and drive away. No straps holding it down? Anyone else do this with no problems of the rzr sliding around? Maybe just chalk to wheels good? Also the trailer I got is a 7x16 tandem axle. Pulled by an 11' gmc Sierra 1500 5.3 liter. Best to keep the rzr over the axles or have it forward more so the engine is more on top of the axles? Thanks for any help.
