Battery Disconnect

What would be the most convenient way to disconnect the 12v rv battery when unit is parked. I see online there are many different products for this purpose. I did buy a pull/push switch from my dealer and he said to wire it with the converter under the dinette bench. Maybe I could place it in a more convenient location with longer wires. I'm thinking in the front storage trunk. My previous Coleman TT had a plug on the tongue you just had to pull apart, very convenient.

The most convenient would be to have the switch located near the batteries so you don't have to go inside to turn it on-off. I mounted a Blue Sea waterproof switch under the propane tanks on my previous Roo hybrid. Some mount them on the side or top of the battery box.

If you already have a pull/push switch and it's not waterproof, I'd look for a location near the power panel. Put the switch in the +ve line between the battery and the power panel.

I'm looking for a good disconnect system as well. Right now I just disconnect the ground wire from the battery, not very elegant, or convenient, but effective. In my case the disconnect needs to be outside of the main unit so I can use the power roof lift.

I'm probably going to go with one of the big plastic rotary switches. Putting it inside the cargo box is a very good idea. My previous experience with these type units has not been good when they are left outside exposed to the weather.

Bat Switch

Go to any marine store for the on/off/bat 1/bat 2/both switch. If you only have one bat, a simple on/off switch will do. Buy enough cable to mount the switch where ever you want it, or install it in line with the current bat cable. The shorter the distance from the bats is better. All West Marine stores have either of the two switches or

I don't think that will totally disconnect the battery. On newer trailers the CO2 detector is usually hardwired to the battery. It will continue to run down your battery unless you install a disconnect of some type.

Now matter how you disconnect the battery. Make sure the breakaway switch is powered when you are driving so the brakes will activate if needed.

Mounted mine in the nose compartment of my Vlite. Got it from Amazon and a 4' auto battery cable(4 gauge) from Auto Zone.

Another option is to use Blue Sea Systems 187 series circuit breakers. They are rated to be used as a switch, are waterproof and ignition protected (won't ignite gas due to spark). All that and you get the added benefit of circuit protection. You can find the Blue Seas 187 series under the Bussman brand name for less cost, but I can't remember what they called them.
