Nice job, looks great!

Thanks man. Your's was one of the installations I studied.

And mine was from studying Bulldog's work. Nice to have each other's experience to keep us moving along on the mods.

Tucson..did you happen to install voltmeters for your system? I'd like to have an LCD or other display that I could toggle from one battery to the other.

That would be nice to have but no, I did not install any monitoring meters. I have checked the system with hand held volt meters but nothing installed.

Just curiousity but what do you plan to primarily drive off your inverter?

Haha....can you say overkill? We're going to use it primarily for laptops etc...but will also use it for overnight stays and running a small refrigerator etc.

Makes sense. I have a portable inverter I use for laptops and now that I have an offorad camping trailer I like to be able to just move it into the trailer when we set up base camp. Not sure of the fridge you have. A lot of us have moved to the 12V fridges like the Engel which don't need 110V. My trailer came with an 85 Qt Waeco that seems to work great.

In theory I could lift it off the trailer mounting and carry it in the back of my 4Runner if I wasn't taking the trailer on a day trip. I haven't tried that yet, but it should work fine.

Great job. Thanks for the write up and the pictures.
