I know I need two breakers in my connection from van battery to coach batteries.

One breaker close to the van battery.
One breaker close to the coach battery.
And the Wirthco Battery Doc in between.

I have plenty of room for a breaker near the coach batteries.
BUT where do you put the breaker by the van battery ????? That space
is really tight.

I'm going 3 feet total from the van battery to the coach battery. Help
me determine what guage cable I need please.

In everyone's debt again!

I'm on the rad right now so I can't find a photo but just put one end of the fuse on the existing + terminal of your starting battery and connect the other end to your cable to your house battery.

I used a circuit breaker like this:

and it fit right in the box that the van battery is mounted in. I do have to open the floor battery cover to reset, but so far, that has not been any inconvenience!

Thank you both.
I just e-mailed my 'sparky' that image from e-bay so he will know it fits.
