Did a similar thing but much less thoughtful of others. Had a switch mounted in the house battery box that couples the two batteries together. Low starting battery? Throw the switch.

Since we have a house battery (AGM, 100 amps), I had something done that I thought kinda cool…

When the installer did all the wiring, I had him mount jumper terminals just behind the driver's door on the outside. They're right there if someone is available to jump us, otherwise I can jump myself by running cables from those terminals to our house battery under the sink.

Never needed it… yet… kinda hoping to go dead once so I can enjoy the concept.

The only caveat is that you shouldn't crank for more than ~5 seconds at a time as the leads will get too hot and eventually blow the inline fuse.
