I have a small 4x7 trailer with wheel chock. Its a tractor supply company trailer( http://www.mytscstore.com/includes/popupWindow.asp?image=1011070.jpg&prodTitle=CARRY-ON TRAILER™ EXPANDED METAL FLOOR UTILITY TRAILER ). I was wondering what the tire pressure should be at?? And is there a way to keep the trailer from bouncing so much?? I will be picking up a rm 125 this weekend and its a 3 hour drive each way so Im trying to make this trip as trouble free as possible.
