I have my battery on the tongue inside a tongue box. I drilled a hole on one side of the box and installed a Harbor Freight 12V switch. Very convenient location--I don't have to open up the tongue box (I keep it locked) to disconnect the battery.
I do have to say however, that the first switch I installed became intermittent, and I finally replaced it with another new HF switch. I'm not sure of the failure mechanism, but I suspect dust as the culprit. Anyhow, I now carry a spare switch just in case. Good thing they are less than $5.
