I minimized the problem by setting the Tripp-Lite inverter to the low charge rate which reduced the current draw. Yours probably has the Magnum invertor and is probably different.
Enjoy your new Interstate. They're a sweet ride.
If you're going to run the a/c with the generator running, the inverter should
automatically switch to "charge only" mode as soon as it detects the generator as a source of 120vAC power. However, it would be useful to switch off the breakers for everything but the a/c. And the televisions, maybe. I've run a/c and TV at the same time with no problem, but that combo does use just about all of the available generator power, with only a few amps left over for battery charging.
The Nova Kool fridge has a useless "feature" that causes it to switch to 120vAC whenever there is a 120vAC power source available, including the generator. However, the fridge will run just fine in 12vDC mode if the breaker is switched off, so I prefer to drive with the fridge in 12vDC mode.
