Calling on the Electrically Intelligent for Power Inverter connection in bed

[BlueOx2500]

I want to be able to charge my Generac battery based generator (the GB2000) with my truck. It doesn't work. When I plug in the Generac the inverter starts to power the GB2000 and then just cycles on / off repeatedly. I guess the draw is too much?

When the GB2000 is plugged into my normal house outlet it does say it is drawing a little more than 400w at times. It seems to vary a little while it is charging. I'm not very electrically intelligent as you can tell.

My 2022 has the 400w AC connection in the bed of the truck and the truck has 1 alternator.

What are my options to make this work, if any? Are there any after market or even RAM produced modifications I could do to make this happen?

Thanks.

I doubt that you can modify the OEM inverter to meet the requirements of your power pack. Your Generac is just drawing too much, even if by a little bit. I would suggest using the "car charger" (I checked the owner manual) cable and extending it to an appropriate DC source. More efficient than an inverter and much less complicated.
