Hey guys, happy 4th!

I have a crazy idea, please let me know how doable it is.

I want to do the mod to my 01 LX to add a second battery. When I used to run a food truck, I had a device called a "Battery Buddy" connected to the deep cycle battery for my generator. When the truck was running, the battery buddy would allow the deep cycle battery to get charged from the alternator, and then it would separate from the system when it would start. It was also great because if my truck battery was dead for whatever reason, I could push a button and use the generator deep cycle battery to start my truck.

Now back to my idea, I'd like to connect this battery buddy to the second battery. Then I would like to take the 12v outlet in my truck and make it always hot instead of switched, and have it get its power from the second battery.

My reasoning behind all of this is bc I was recently transferred to a different location for my job and the building I was put it has A HUGE cockroach problem. I brought food in once and the minutes I shut the fridge door, 3 roaches made a quick dash for the fridge.

If I had such a system in my truck I could put a small 12v cooler in my trunk so I could keep food and not starve for the next 4 months while I'm working a full time job and am a full time student at night.

Long term, I could also use it in camping trips with the family.
 
Thanks!

I already know there are a lot of threads on the dual battery, didn't see anything about turning an existing 12v switched outlet to an always live outlet though.
