Most "modern" vehicle charging systems are only putting out 13.2V-13.5V AT THE FRONT BATTERY. YOU ARE NEVER GOING TO GET ENOUGH VOLTAGE TO CHARGE YOUR HOUSE BATTERY !
I think you may be misunderstanding. I intend to tie my house battery system to my towed Honda CR-V to make sure the CR-V battery isn't drained by my Blue Ox Patriot brake, while towing. My house batteries are constantly being charged while on the move and I am tying them to the Honda battery so it doesn't drain. The point of the diode is to prevent the Honda from draining back to the house batteries in case there is a voltage differential in the wrong direction.
