It certainly would be a long haul for us and the way run all of our stuff to last a couple of weeks camping off the power grid.
I went the route of making our camper using less and less DC Power but our game plan was to be able to use all of the things we wanted to have running using the battery bank and running an Inverter. The game plan was to drain down the batteries to around 12.0VDC by 8AM each day and during breakfast run our 2KW Generator and recharge our batteries back up to to their 90% charge state in a short three hour generator run time. This requires using smart mode battery charging...
We can make 12-14 days of 50% to 90 charge cycles on battery bank but after that we must do a full 100% charge state which would require the generator to run around 12 hours. Most camp grounds we go to would not allow us to run the generator that long so that's usually when we come back home.
Adding SOLAR PANEL to to the mix would really reduce our depending on the generator so much...
In your case adding a disconnect switch would be an easy chore to do. Sounds like you only have a single battery installed so one of these terminal switches would probably work great.
These type of battery case side mount switches are popular as well
