Starting batteries instead of deep cycle
So I’ve got a theory... Deep cycle batteries are designed to slowly discharge low current for a long time. Starting batteries are designed to put out high current for short periods. Generally, p...

No, just no to the OP.
Starting a motor is WAY more draw than any inverter you would be using. Your inverter is still only requiring a slow discharge from the battery. I'll stop here
I got the much-touted two-six-volt Trojans. Now my inverter won’t run my coffeemaker.
I had two 12-volt Costco marine/RV batteries. I always just used regular starting batteries before that. The screwy thing is, they would run it.
These real deep cycle Trojans just can’t put out enough current at once.

I'd have to do more research. My first thought is not that the batteries were not up to snuff, but maybe the wiring or something else is happening on this one incident. If you are pulling so many amps that a marine battery cannot keep up then I suspect that you are demanding more than 1000-1500 watts of a coffee maker or that there are other issues preventing a free flow of amps to the always inefficient inverter.
I have started cars with one marine battery and I do not suspect that a coffee maker on an inverter requires more amps than a starter motor.
This rigidness of resisting the camping lifestyle when camping seems to be costing RVers a lot of money (in this case for batteries they really do not need). Getting in an RV mindset means using RV-friendly coffee makers, which probably will run on propane, not electricity. Many things RV are designed to be efficient on what the RV offers. Those that want the exactness of house living usually buy brand new class-A motorhomes with huge generators they plan to run all the time.
I would ditch the idea of creating enough power to run a house and get on board with the camper life.
I have 2-0 “double-ought” cables that are about two feet long. That sure isn’t the problem.
I’m talking about electricity and making some gear I own work the way I want it to.
Not whether you think I “should” have my electric coffeemaker.
I can throw a few batteries in and still be WAY below what lots of guys are spending on new F450s and new Rams to carry their camper on.
This setup worked on regular old batteries. That’s probably what I should go back to.
