Depends on the trailer and the trailer's options. If, like my 318SAB, you have a remote control, you will probably find that the disconnect switch will disconnect everything except those items controlled by the remote control. The remote's control board is mounted directly to the battery prior to the disconnect switch and everything controlled by the remote is still live even with the switch in the "Off" position. For instance, on my 318SAB, with the switch "Off", my landing gear, all three slides, docking lights and awning all still operate, however, all the inside devices are disabled that are not controlled by the remote. Not a true "disconnect switch", but, it will kill the radio, power to the water heater's control board, power to the refrigerator's control board, etc. eliminating some of the drains on the battery.
A lot of folks will mount a "true" disconnect switch in the battery's cable as it comes off the battery and before the remote's controller board, but, since I have AC power to mine 24/7 (I have an RV hookup at the sticks and bricks) I don't worry about it and if I want to disconnect the power, I just pull the cables off the battery.
