Hello, I have a 2022 Big Country 3560ss. I was told that to c9nvert to lithium, I may have to change the converter. Ive also been told that 2022 and moving forward, all converters wpuld be compatible. I have attempted to locate the xonverter with no luck, I have found the inverter and transfer switch, but no luck with the converter. I looked beneath the breaker panel, and fuse panel. Not there either. Any help would be apprecuated.
