Update battery capacity on Thor Sequence 20L

[jgk]

Hello Everyone.

Just purchased a 2022 Thor Sequence 20L. It comes with (2)100ah lithium batteries, upgraded alternator/generator and 190W solar. I'm finding I can only get about 1.5 hours using the air conditioner before the batteries drop off, which is mostly fine but want to be able to boondock overnight without worry about starting the Promaster.

Has anyone upgrading the lithiums yet on the Sequence 20L? Was thinking about purchasing a 300ah lithium and just adding to existing battery bank under the drivers side bed or under chassis.

Thanks.
