Negative is usually easier. Just one cable between battery and ground.
It doesn't matter which one you use (- or+).

For a disconnect switch either is fine as long as the ONLY thing connected directly to that battery terminal is one side of the switch. Note that you will need to remember to turn on the switch before towing in order to enable break-away braking.

No matter how much arguing will take place in yet another thread discussing which post to use... it makes no difference which one you choose.

The easiest thing to do is just physically disconnect the negative cable.

You mean getting out a tool and physically unscrewing a bolt or clamp is easier than twisting a knob on a disconnect switch?

absolutely. I have a cheap ratchet and socket right in my battery box. Takes 5 seconds and I don't have to worry about the landing gear other stuff that comes off the battery before the panel still causing draw. for the price and time of installing a disconnect Ill keep unhooking my negative.

I have two batteries up front. one in the front compartment by landing gear and one in a small side compartment in front of the basement. They have multiple items coming off with inline fuses. For the time it takes me to disconnect it would be a mess to try and add one disconnect that would actually turn everything off.

That's why most folks I know just install the cutoff on the ground that goes to the frame. One wire, and you can spend from $6.99 to as much as you want for a cutoff switch. Then you won't wear out your post and clamp bolt
But everybody does what makes sense to them. No worries. Happy RVing!

Landing gear motors, awnings and the like are NOT parasitic draws as they only draw power when you press the button.

Our trailer is next to the house and the battery disconnect is almost always off unless I am doing something to it. I just went outside to opened up the slide and then closed it for something I had to do. Easy peasy...turn the switch on, do my thing and then turn it off. Couldn't even imagine taking the battery cable off and on every time.

Putting the disconnect switch on neg or pos doesn't matter electrically. It just a convention for positive. If the negative is much easier, do it that way.
