ReVo Leveler is an aftermarket product for trailers, bumper pull and fifth wheel, that when you locate your trailer on a site you press a button and it will tell you what board thickness is needed and which side of the trailer needs raised to be level left and right. No more guessing or relying on bubble levels. Another button tells you when the trailer is in the correct disconnect position, another for level front to back and a fourth for connect position.
