I've run into a few people who don't use their inverter. It is hard for me to imagine why anyone would not want the full capability of their electrical system. Our inverter is on all the time, if we don't have AC in the coach, something is broken. We've run that way since we began in our first motor home, a 1994 Dynasty. We have a 4 battery system, a 3000W inverter and run our household refrigerator with icemaker, it is never off. We can go overnight running the furnace and the refrigerator on the 4 batteries without a problem. What do we use the electric for all the time? Computers, clocks, TV system, coffee maker, other kitchen appliances, an electric razor, power tools, just all the things we use when we are in a normal house. Louise hates resetting clocks and I enjoy the convenience of just plugging in when I need electric. Yes, we have a generator and it is essential for the big things and recharging but I don't want the noise of that running all the time. Besides, if you figure the actual cost of running the generator, not just fuel but include maintenance costs, it runs you about $2.50 to $3.00 per hour (our actual costs).
I do find four batteries enough for us and if you aren't using the inverter full time you could probably get by with fewer than 6 batteries. The only downside to six batteries is weight and the cost of replacement. Both are minor in the grand scheme of things. If I had space for six batteries I'd be glad to have them.
