You are very lucky. That might work in an occasional use vehicle, but not usually in a daily driver.

Normally batteries don't wear evenly and all connections aren't perfect so they don't charge at the same rate. This usually leads to one battery out of a parallel set getting boiled dry while the weaker one stays normally charged. They then discharge differently so every cycle gets worse.

There is a good reason for the isolator setup. You never kill a battery by the above scenario or can't start it because you left something on by mistake or overuse.

I also agree with the marine battery for the second one. Car batteries can go bad fast if totally run down.
