The 10 amp fuse you pulled is likely for the break away brakes. Put it back.
A negative disconnect will probably also disable the break away brakes so you can't pull the trailer on a road with it turned off.
I'd just use a circuit breaker in the positive main wire.
Breakaway brakes are not supposed to be fused.

I would go with a switch and the Negative cable is a good spot or it.
I've seen a lot of argument on negative or positive. but I favor Negative.
On many RV's there are multiple POSITIVE wires is one reason
Another is if you are removing the battery and start with the POSITIVE lead.. if the swich is off and the wrench slips. No harm done
But if the switch is in the positive you can end up with a nasty burn and a melted wrench and worse.
Multiple positive wires can be combined.
Always remove the negative cable from the battery first. That way, if the wrench slips when removing the negative cable, no problem. If the wrench slips when removing the positive cable, no problem. In other words, the wrench slipping is never a problem.
If the switch is on the positive, you can’t get a nasty burn and a melted wrench and worse because you took the negative clamp off first.
