    I just brought a Reefer trailer that is a spread with independent sliding axles. I have a question about the box that has three switches that deal with the dump and axles themselves. I have heard that I can have switches setup in the cab to deal with the dumping of the axles. are both axles dumped at the same time or what ? What is the switches called ? I would like to look into getting something like them installed in my truck.

    I have one that only has rear dump or dump all, then the isolation valves for sliding the axle, you can plumb in dumps on both either to the box or to a junction box and run to a plug for the cab
