Do I need the Reverse-A-Matic(TM) RM-50 or the RM-60?
1. RM-50 (PN#200501-OEM) – The RM50 can be used for three and four axle trailers to meet there SPIF regulations. Two axle trailers can use the backup beeper functions. 2. RM-60 (PN#200506-60OEM) – If you have a five or six axle trailer you need the RM60 to meet all SPIF regulations. The RM60 has many excellent features that can be used on other trailers. The Steer axle lock and the four-way flasher lift are two of them.
