Battery cut off switch
I want to put a battery cut off switch on my TT so I do not have to keep removing the cables when I store. The question, should I put on one or should on two to cut off both sides of the battery?

The reason some instructions say to place in the negative is because they are considering a powered vehicle, not a trailer. In a vehicle the negative is preferred. However for a trailer that is required to have brakes the breakaway is required to be operable when towing.
If the disconnect is left open, the breakaway will only work if it is in the positive and wired in front of switch.tenbear wrote:
Is there a requirement that the breakaway switch be wired directly to the battery? I don't know why you would ever be driving down the road with the battery disconnected, but just to cover all the bases it is probably best to wire it with the breakaway switch not affected by the disconnect switch.
The breakaway is required to be operable. How it is wired is discretionary providing it is operable when towing. I guarantee that sometime, somewhere, someone will tow with the disconnect open. If not you then the next owner.F105 wrote:

It won't cause damage providing it never comes off the hitch and needs for the breakaway to work. It could be considered negligence if the breakaway is made inoperable and people are injured.
I think you mis-understood what I meant by my saying I tow my FW with the battery disconnect switch disconnected.
The brake disconnect switch is hot wired to the RV battery and is independent of the battery disconnect switch. Neither the RV manual or the battery disconnect switch have any warning to not disconnect the battery when towing.
