Make alternator charge house battery better
Would this charge house battery better? Run a new heavy alternator wire to house battery first and use existing wire that goes from chassis battery to isolator to converter to house battery to charge ...

That sounds like a bad plan to me for two reasons. First, if the isolator fails, your chassis battery won't charge at all, and you'll be stuck sooner or later...probably sooner. Second, the alternator's voltage regulator will be regulating based on the chassis battery, but the output mostly going to the house battery, leading to poor voltage regulation and (if the isolator is anything fancier than a solenoid) quite possibly dramatically overcharging the house battery.
Running a heavier wire from the isolator to the house battery would probably help, and making sure all the connections are good and tight won't hurt. Ultimately, you may be limited just by the alternator output capability (and how much it exceeds the chassis electrical requirements), and no amount of fiddling with connections can help that.
